This is the 24xDPST version of our 40-110/40-115 range of reed relay switching modules which are available in both Changeover (SPDT) and Normally Open (SPST & DPST) configurations. Connections are made via a front panel 96 pin male micro-D connector. General purpose reed relays are suitable for the construction of small switching networks, for slave switching larger relays or for operating external devices (e.g. lamps, solenoids etc.). To simplify inter-relay wiring, interconnection points are built onto the circuit board thus easing the construction of complicated wiring.
