Description
The Model 2681 Voltage Band Monitor is a dual set-point voltage
monitor. Input voltages between the upper and lower set-points
will cause the output contacts to pull in (contacts 1 &
3 closed) and the LED indicator to illuminate. Input voltages
above or below the set-points will cause the output contacts
to drop out (contacts 1 & 4 closed) and extinguish the
LED indicator.
The Model 2681 is available
in AC or DC versions. AC models of the 2681 are not frequency
sensitive and can be used on systems from 50 to 400 Hz.
The voltage set-points are screwdriver adjustable over a
wide operating range.
The SPDT output configuration
is identical to the configuration of general purpose relays.
This unit requires a standard 8-pin socket for mounting.
