MS1X Series Trip Circuit Supervision Relays
The MS1X series of supervision relays has been designed as a simple& cost effective device for monitoring the condition of fuses, circuits & breaker coils in protection & control circuits. Local visual indication system failure is provided by a large ultra high intensity LED.
Remote indication is made possible through the normally closed output relay contact provided. All MS1X model relays are characterized by their compact size, plug in connection base & simple panel mounting configuration.
Choose from the MS1X10, MS1X20 & MS1X30 for the functionality to suit the monitoring application required.
-
MS1X10 trip supply supervision
-
MS1X20 trip circuit supervision with CB closed
-
MS1X30 trip circuit supervision with CB open & closed
MS1X10 trip supply supervision
- The MS1X10 Fuse Supervision relay monitors the condition of fuses & DC supplies in protection & control circuits.
MS1X20 trip circuit supervision with CB closed
- The MS1X10 Fuse Supervision relay monitors the condition of fuses & DC supplies in protection & control circuits. In addition to the DC supply supervision function, the MS1X20 relay also supervises the CB coil.
MS1X30 trip circuit supervision with CB open & closed
- The MS1X30 Trip Circuit Supervision relay monitors the condition of the trip circuit supply, trip circuit wiring and circuit breaker operate coil continuity. The MS1X30 relay is comprised of two electromechanical output relays which are wired across the protection trip contact and the circuit breaker a and b pallet switches. This results in the alarm relay being normally energized provided the trip supply, the trip circuit and the circuit breaker coil are all healthy.
