Wiring a 170 ADM 690 51 as a 170 ADM 690 50
2-Wire Sensor with a 2-Wire Actuator
The diagram below shows field wiring for a 2-wire sensor and a 2-wire actuator.
4-Wire Sensor with a 3-Wire Actuator
The diagram below shows field wiring for a 4-wire sensor and a 3-wire actuator. When using 3-phase current for supply L1, 1L1 and 2L1 must come from one phase.
