PLC Compatibility
In order for a solid state, 2 wire, AC sensor to be directly compatible with a PLC, two conditions
have to be met:
1. Leakage current: (I off) less than 1.7 mA (Off state)
2. Load current: greater than the sensor minimum load current (ON state). Typical PLC
input currents (load current, I load) are 12-16 mA. Typical values for PLC input resistance (Rin)
are: 7.5-10 kΩ.
For sensors which do not meet both of the requirements, a Bleeder Resistor (Rb) has to be
wired in parallel with the load.
For each of the two situations, the Bleeder Resistor parameters have to be calculated as shown
below. The smaller value should be selected for the application.
