Magnecraft 831 Series Voltage Sensing Relay
Capable of Monitoring⁄Reacting to Over & Under Voltage Conditions
The 831 relay is a single phase AC voltage sensing device that is capable of monitoring and reacting to over and under voltage conditions. It is designed to be wired across terminals A1 and A2 with the voltage being monitored. Two LED lamps indicate when input voltage is present (Green LED) and when output is energized (Red LED). The umax dial sets the upper trip–point for the voltage sensor. The umin dial is a percentage of the umax dial and is used to set the lower trip–point for the voltage sensor. The timing dial delays the transfer of the contacts, from 0 to 10 seconds, when a set point has been violated.
