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.
