input mode
connector
Not installed
24 V input mode (0-5 V: logical low, 11-24 V: logical high). (default)
1-2
24 V input mode with 2.2 KOhm pullup resistor, instantiated on AUX_IN+ pin.
2-3
24 V input mode with 2.2 KOhm bleeder resistor, instantiated between AUX_IN+ pin and
AUX_IN- pin. Needed to support a 2-wire proximity sensor.
3-4
TTL input mode (0-0.8 V: logical low, 2.0-5.0 V: logical high).
Output mode connectors
The output mode connectors are standard, 2 mm spacing, 4-pin male connectors
that allow you to set the output mode of an auxiliary output signal using a jumper.
The description of possible jumper positions is as follows

24 V output mode. Up to 100 mA sinking/sourcing current when output is turned
on/closed. (default)
1-2
24 V output mode with 2.2 KOhm pullup resistor, instantiated on AUX_OUT+ pin.
3-4
TTL output mode. Logical high level made possible using an internally isolated 5V
through a 300 Ohm pullup on AUX_OUT+ pin.
