TRANSISTORISED RELAY MODULE PART No. SS1-H

12 volt dc supply. 2 pairs of voltage-free changeover contacts. Contacts rated 5 amps @ 240 volts. Contact material silver cadmium-oxide for switching high voltages at high currents. Much used in the security industry for switching sounders, strobes, lighting and many other applications. Extra heavy duty terminal blocks fitted to facilitate 1.5mm mains cable.

The SS1-H relay module has two transistorised inputs; a positive and a negative one which can both be used simultaneously (eg., for latching purposes). The transistorised inputs will trigger from 5 or 12 volts. These inputs (being transistorised) draw very low current so avoid overloading the trigger source device.

Many of our customers use the SS1-H as a compatible replacement for the CASTLE CARE-TECH T-relays.

Dimensions are width 48mm x length 50mm x height 30mm.

These modules are solidly built and tested to a high standard in the UK by STS. Three adhesive-backed mounting feet included.
