Additional features
Interface relay. This device accepts a variety of input conditions (Voltage, Logic, Closed Circuit and Open Circuit) for interfacing various signals via voltage free DPCO contacts. The S312T is similar to the S312N but its action can be delayed by between about 3 and 60 seconds. This can be adjusted with the on board potentiometer. This can be a useful feature where it is necessary to delay one action slightly to allow another.
