The 40-110/115 range of switching modules are available in both Changeover (SPDT)and Normally Open (SPST & DPST)configurations.Connections are made via a front panel SCSI 2 type 96 pin male connector. For applications requiring improved bandwidth and crosstalk performance please look at our 40-120/125 range of shielded reed relay cards. General purpose reed relays are suitable for the construction of small switching networks, for slaving up to larger switches 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.
