Features
E-1071-353
The E-T-A Solid State Remote Power Controller E-1071-353 is a double
relay with protective function both for resistive and inductive DC 24 V
loads. It is particularly suitable to control upward/downward and forward/
backward movements. Failure of one channel will also cause the other
channel to disconnect.
