The Macromatic THR-3816U is a programmable Time Delay Relay. This encapsulated, multi-range, multi-voltage relay has an input voltage of 24-240V AC and a 12-125V DC. It is a multi-function unit with 4 different settings and a time range of 0.1 sec to 100 minutes. The THR-3816U has an output of 10A SPDT which accommodates pilot duty and fractional HP loads. The time delay can be changed either on the unit or remotely. Featuring dimensions of 2" x 2", the encasement of the unit allows it to be used under more extreme conditions. Settings are chosen using DIP switches.
