Digital Input Module EP-1804 Connection Diagram EP-1804
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 110V AC and 230V AC. Solely AC measurements can be run.
