Connection 1:

X1: Signal connection, digital outputs, D-Sub 25

The EM2042 digital output module transmits the binary control signals from the automation unit on to the actuators at the process level.

The 16 outputs deliver load currents of up to 0.5 A, although the total current from all the outputs must not exceed 4 A.

The signal connection is made through a 25-pin D-Sub socket.

The outputs are short-circuit proof and protected against inverse connection.
