The digital input module EP-1804 can detect up to 4 binary control signals. One sensor can
be connected to each connector using a 2-wire connection. Both L and N connections of
each input are bridged internally. The four inputs are galvanic isolated, they can be
supplied with input voltages between 110Vac and 230Vac. Solely AC measurements can
be run.
WARNING
A status LED is assigned to each channel. All signal lines must be supplied from the same
power system.
