2681-230VDC
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.

2629
The Model 2629 AC/DC Voltage Monitor is designed to continuously monitor any AC or DC voltage from 15 to 260 volts.Input voltages below the set-point cause the output contacts to de-energize. Input voltages above the set-point cause the output contacts to energize. The dead band between pull-in and drop-out is less than 5%.
Dip switches are used on the Model 2629 to choose between AC and DC voltage monitoring, and to select one of the eight trip level ranges. Each trip level has a 35 voltage range, with a 5 volt overlap between the ranges. The unit has a screwdriver adjustment to set the exact trip point within that 35 volt range.
