Description

The terminals for the following are located on the input and output module IO204:
•
10 binary inputs
•
4 binary outputs with 4 standard make contacts (type S)
•
4 power relays for controlling 2 motors (forward/backward) with a common auxiliary voltage supply V
+, V -
aux
The power relays operate in interlocked mode, that is, only one relay of each switching pair picks up at a
time thereby avoiding a power-supply short circuit. Note the polarity specified in the terminal and
connection diagram.
The connections are distributed over three 14-pole voltage terminals.
