Inputs
The inputs are connected to a common ground connection (GND
I/O
at X2, X4 or
GND at X9).
Input level: 24 V
DC
The input circuit protective resistor of
3.3 k
Ω
corresponds to 7 mA nominal
driver current at 24 V
DC
.
Signal level Low: < 0.4 V
DC
Signal level High: 20 – 30 V
DC

Outputs
The overload-safe outputs are equipped with protective diodes to protect the internal
circuitry. In the case of inductive loads (e.g. relay) each output should be additionally wired
with a protective diode mounted near the load in order to avoid EMC problems.
Max. 1 A current each output
Up to 3 A for all outputs
