Monitoring Relays
A Monitoring Relay is a protective control device. The basic functions are to receive input signals, monitor and determine them, and output an alarm signal if a set value (threshold) is reached. Monitoring Relays monitor power supplies (voltage, current, power, phase), temperatures, and other analog signals and detects abnormalities in machines and equipment by determining values against alarm thresholds.

Auto Reclose and Sync Check
Operating records for overhead power lines reveal that most faults are of a transient nature (e.g. lightning induced) & that service interruptions may be minimized by use of automatic reclosing of circuit breakers. An automatic reclosure of the circuit breaker, after the fault clears, provides improved service continuity & system stability. The 1B230 Series Reclose Relay provides for single or double shot automatic reclosing of circuit breakers, following interruption of supply due to a fault in the system.

Voltage Protection
Are solid state voltage sensing relays with electromechanical output contacts built in a fully draw out case format. Designed for application on AC & DC voltage systems, these relays are ideally suited to monitor power supply voltage levels wherever high accuracy and reliable, maintenance free operation is essential. All power to operate the relays is derived from the sensed input voltage therefore an auxiliary supply is not required.
