Note:

1. Power must be supplied to the three-wire sensor via the positive power supply terminal or from an independent power supply.

Two-wire sensors must satisfy the following requirements:

Residual voltage:

4 V max.

Current leakage:

1.5 mA max.

The lower limit of control output:

3 mA (Use a bleeder resister to eliminate this restriction.)

2. Consumption when all 8 input/output points are ON. Excludes external sensor current for Input Terminals and external load current

and error load current for Output Terminals.
