Assigning inputs to each other
The digital input module F-DI 8×24VDC HF has 8 fail-safe inputs, DI
combine two of these inputs each to one input.
You can combine the following inputs:
● DI
● DI
● DI
● DI
The process signals are provided by channels DI
Wiring
The wiring is carried out on the matching BaseUnit (Page 13).
Sensor supply
The sensor supply can be powered internally or externally.
Wiring diagram – connecting a two-channel sensor equivalent
A two-channel sensor is connected equivalent to two inputs of the F-module for each
process signal (1oo2 evaluation).
Figure 5-4
You can also supply the sensor by means of an external sensor supply.
