Note: 1.
Power must be supplied to the three-wire sensor via the positive power supply terminal or from an independent power supply
.
T
wo-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 T
erminals and external load
current
and
error load current for Output T
erminals.
