DESCRIPTION
The
Model 260 Voltage Sensor
is a single setpoint voltage
sensor. Input voltages above the setpoint cause the output
contacts to energize
(contacts 1 & 8 closed)
. Input voltages
below the setpoint cause the output contacts to de-energize
(contacts 1 & 2 closed)
. The dead band between pull-in and
drop-out is less than 2%.
The standard unit has a screwdriver, or fingertip adjustable
setpoint range of approximately 35% of the maximum
voltage. This device can also be provided with a factory
calibrated trip point.
AC versions of the Model 260 Voltage Sensor are not
frequency sensitive, and may be used in systems from 50Hz
to 400 Hz. DC models are not polarity sensitive.
This device requires a standard 8-pin socket, such as Time
Mark’s Model 51X120.
