RM Series - A quality range of power relays designed for chassis mounting via mounting tabs, connections via 6.3mm push on terminals. Available in three types; DPCO 16Amp, 3PCO 16Amp, DPCO 25Amp. These relays are ideal for switching large resistive loads such as heating elements and lighting loads when perhaps the use of a contactor would be the normal consideration. The relays have as standard a flag indicator and are CE marked with many international approvals including UL and CSA.

TRP693 Range - A high quality range of CE marked traditional pin out 11 pin 3PCO plug in relays, nominally rated at 10Amps/250VAC. The relays benefit from every customer required option as standard, namely both mechanical and electrical indication via a mechanical flag and a high intensity LED. DC coil relays (TRP6930) also have included within the relay a protection diode fitted across the coil as standard. The relays can be manually tested by a momentary action push button. Coil voltages available are from 6VDC to 240VDC and 6VAC to 240VAC. Clearly marked on the relay case are the connection details, approvals and the CE mark.

MT3 Range - The Shrack MT series relays is a high quality range of traditional 11 pin relays (3PCO) nominally rated at 10Amps. The relays have as standard a push to test button, a locking lever and flag indicator. A white marking area on top of the relay facilitates easy relay numbering. The MT series has a number of international approvals including; UL, CSA and VDE.

A high quality range of CE marked standard pin out 4PCO 14 pin plug in relays, nominally rated at 5Amps/25OVAC. The relays benefit from both mechanical and electrical indication via a mechanical flag and a high intensity LED. DC coil relays (TRP3140) also have included an internal protection diode fitted across the coil as standard.

The relays can be manually tested by a momentary action push button, the same push button can be pulled outwards to give a locking facility. Standard contact material is silver but on request the relays are available with gold flashed contacts for long term assurance of low level signal switching (suffix part number GF). To differentiate between AC and DC coils in the same installation the push button is coloured red for AC coils and blue for DC coils. Coil voltages available are from 6VDC to 240VDC and 6VAC to 240VAC. Clearly marked on the relay case are the connection details, approvals and the CE mark.

TRP312 Range - A high quality range of CE marked DPCO 8 pin plug in relays in the "14 pin style", nominally rated at 10Amps/250VAC. The relays benefit from every customer required option as standard, namely both mechanical and electrical indication via a mechanical flag and a high intensity LED. DC coil relays (TRP3120) also have included within the relay a protection diode fitted across the coil as standard.

TYPE: PYF-14AEW - Our most popular 14 pin socket, complete with a fixed marker tab and a screw driver release tab.
TYPE: PYF-14BE & PYF-14BE/3 - “High sided” 14 pin sockets with tunnel clamps. A triple deck version, the PYF-14BE/3 allows segregation of voltages, coil terminals being on one side with two A2 terminals. All changover terminals on the
opposite side.
TYPE PI-35BE - Fully protected 5 pin relay base. The PI-35BE has rising tunnel style clamps. The PI-35BE is for use with the RTB14 and RTB74 relays.
TYPE PI-50BE & PI-50BE/3 - Fully protected 8 pin relay base. The PI-50BE and PI-50BE/3 has rising tunnel style clamps. The PI-50BE/3 is a “triple deck” base with the coil connection on one side of the base and all the change over
terminals on the other side, thus achieving voltage segregation. The PI-50BE and PI-50BE/3 is for use with the RTD14 and RTE24 relays.
TYPE PF-083BE (8PIN) & PF-113BE (11PIN) - Fully protected sockets with coil and common terminals at one end and the change overs pairs at the other end side by side, thus enabling very easy wiring changes and corrections. The terminals are rising style tunnel clamps, up to 2 x 2.5mm cables can be accepted. The sockets also have a white marking area.
TYPE PYF-08AE - Our 8 pin socket to compliment the TRP3125 relay.

UNI-1LR and UNI-2LR - An attractive modern designed 16 Amp AC1 latching relay in a din rail mounted modular style housing of 1.5 modules width (27mm). The relay features the facility of double deck terminals thus enabling the timer to be available also in both a SPCO and DPCO versions. The latching function is commanded via three different trigger inputs. A green supply on LED is featured along with a red LED to indicate relay output status. All terminal details and information along with the CE mark is clearly marked on the sides of the housing.

NR8000 Series - A din rail mounted ˜pulse on, pulse off" latching relay, modular in construction and thus suitable for mounting within consumer units. The relay is DPCO rated at 16Amps and benefits from a continuously rated coil so that if circumstances dictate the coil supply can be left permanently on. The relay requires a supply to the coil to energise, on removal of the supply the contacts remain in an energised position. Re-connection of the coil supply and the contacts will de-energise. The relay can also be manually switched via a front pushbutton and a flag indicator is also fitted. This relay is particularly suitable for duty changeover of pump sets either by demand or time, however, other applications are limitless.

Miniature interface relays available as SPCO and DPCO, suitable for PCB mounting or plug in into Din rail mounted bases. The relays are compact in construction being of low profile and fully sealed. The PCB pins are very strong and, therefore, are hard to bend when they are inserted into the Din rail sockets (this has been a weak point in the past with this style of relay). The relays maybe miniature in size but with regards to current switching capacity, they are large. The RTB14 being a 5 pin SPCO relay switching 12Amp, the RTD14 being an 8 pin relay but SPCO switching 16Amp (the current is shared across two sets of output pins), the RTE24 being an 8 pin relay DPCO switching 8Amp. These relays due to the compact size are without any indication, however when Din rail base types PI-35BE, PI-50BE and PI-50BE/3 are utilised a range of LED modules, suppression modules and LED modules can be plugged into these bases.

UNI-1R and UNI-3R - An attractive modern designed 16 Amp AC1 power relay in a din rail mounted modular style housing of 1.5 modules width (27mm). The relay features the facility of double deck terminals thus enabling the relay to be available also in both a SPCO and 3PCO versions. Coil voltage is determined via the connection to different terminals. LEDs are fitted to indicate relay output status. All terminal details and information along with the CE mark is clearly marked on the sides of the housing.

A din rail mounted tri-voltage modular latching / sequence relay with a selectable memory option. Outputs are four individual single pole normally open contacts. The unit is programmed via three front selector switches. Switch 1 determines the number of relays in play, switch 2 the function of the latching / sequencing of the relays, switch 3 selects if the memory function is required. The unit requires a permanent supply to the coil and operation is then achieved by using up to three volt free trigger commands from A1 onto terminals FWD, BCK or RESET. The unit reacts to the leading edge of a trigger input only. If required the trigger input can then be held continuously, if then a leading edge is then seen on any of the other inputs the unit will operate accordingly. A trigger to FWD will cause the unit to switch the relays in a forward manner, whilst a trigger to BCK will cause the unit to step back a position. A RESET trigger will cause the unit to reset back to the first (start) position.

Miniature interface relays available as SPCO and only with DC coils. The RTB74 is a special sensitive coil version of the RTB14 relay, the RTB74 has a much higher coil resistance and hence a lower coil consumption. This makes the RTB74 relay ideal for use on converting BMS and PLC analogue output voltage signals to digital outputs when there is only limited power behind the signal. In particular the 12VDC version is used extensively with the 0-10VDC output signal from "Trend Building Management Systems".

Other applications include converting transistor outputs to digital or when utilising a power supply and overall power consumption has to be kept within limits. The RTB74 relay can be PCB mounted or be used with a Din rail socket, however it is not recommended that the plug in LED modules are utilised if the relays have been selected because of the low coil consumption, using the LED module will of course increase the overall current consumption.
