WIRING OF ANALOG INPUTS – ISOLATED SENSORS
3.13.1 Tristate inputs
Analog inputs can be used also as binary or tri-state, i.e. for contact sensors without or with circuit
check. The threshold level is 750Ω. In the case of tri-state, values lower than 10Ω and values over
2400Ω are evaluated as sensor failure (short or open circuit).
