Dataforth Data acquisition system with discrete relay output

The MAQ20-DORLY20 module offers 20 isolated SPST latching relay output channels that can switch between 2 A at 30 V and 0.4 A at 150 V. Each channel has contact state readback to verify the physical output state. Relays can be controlled individually or in blocks and have user-configurable default output states that are set upon power up, power loss and module reset to ensure failsafe operation. Other features include advanced output functions, user-defined logic polarity and fast switching times. Field output connections are made through high-density spring cage terminal blocks. Reserve power is stored and used for predictable shutdown to user-defined relay states upon loss of module power.
