Digital Outputs
Digital Outputs (Standard)
The digital outputs are compatible with digital inputs of types 1, 2 and 3
(IEC 61131).

When several outputs supply current simultaneously, the maxi‐
mum allowed total current of these outputs must be taken into
account. According to the number of outputs, the total current
must be related to to 4 or 8 outputs.
3)
In the case of inductive loads with a greater energy content, an
external free-wheeling arm must be installed. The effective ter‐
minal voltage must be < 25 V.
4)
The maximum energy content depends on the switching fre‐
quency f of the outputs

Digital Outputs
●
The digital outputs have been realized with high-side
switches. This means that these outputs only can actively
supply current.
●
The energy absorption capacity of the outputs is used to limit
voltage peaks caused when inductive loads are switched off.
Limit voltage peaks by using free-wheeling diodes directly at
the relay coil.
