10 DI3/OC1
Digital input/output, configurable.
Open collector: Maximum 24 V resistive or inductive.
4 AI1
External sensor.
Pressure sensor: Pressure signal, 0.5 to 3.5
V. Connect the white wire to this terminal.
2 DI1
Digital input, configurable.
Digital input 1 is factory-set to be start or stop
input where an open circuit results in stop. A
