DA255: Quad relay

Quad universal relay unit with 12V DC operation. This relay has four completely independent SPCO relays on one PCB.

The DA255 quad relay PCB is available with or without a mild steel enclosure. Typical uses include changing the polarity of signals and switching higher currents and voltages. It can also be used as an interface between different systems, e.g. intruder alarm to access control or fire alarm to access control. This unit can also be used for isolating communicator trigger inputs.
