Connecting safety I/O interfaces

Refer to this section before connecting I/O interfaces to external devices.

Source input

This is an input circuit in which the anode of the photocoupler is the input terminal. Transmit signals from a source (open-
collector) type transistor output, relay switch, etc.
The wiring differs depending on the device to be connected and whether the test pulse diagnosis is performed. For the test
pulse diagnosis, refer to "FUNCTIONAL SAFETY" in the following manual. (Rated current: 5 mA, maximum current: 10 mA)
