DESCRIPTION SPECIFICATIONS

MODEL 160B120 160B240 160B480

The Model 160B(R) Voltage Sensor is a single set-point voltage sensor. Input voltages above the setpoint cause the output contacts to energize. Input voltages below the setpoint cause the output contacts to de- energize. The dead band between pull-in and drop-out is less than one percent.Wiring connections are made to 1/4” quick connect terminals. Standard versions have a 2 second restart delay. The ‘R’ versions of the Model 160B have a fixed 5 minute short cycle delay. The Model 160B has a screwdriver adjustable setpoint range of approximately 35% of the maximum voltage. The Model 160B is not frequency sensitive and may be used in systems from 50 to 400 Hz.
