0-10V Signal binary or sequence or step of 3 volt free changeover relays

The IO/DOM3 digital output module is microprocessor based and designed to provide sequence, step, heat/cool or binary control of 3 Volt free relays from a
0-10 Volt control signal.

In sequence or step mode the module incorporates an optional time delay setting 0-100 seconds to prevent short cycling and for soft start of switch ON after power failure. There is also an input to reverse the control output sequence.

The other operations are selected on the DIL switches and the different switching combinations are shown in the tables.
