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:
Current leakage:
The lower limit of control output:
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.
