Monitor DC supply and trip circuits
Supervise DC voltages and breaker trip circuits continuously, raise alarms on faults, and provide mechanical flags for fast diagnosis.
Why Reyrolle 7PG17?
Reyrolle 7PG17 interposing and supervision relays keep protection and control schemes dependable and visible. This electromechanical range covers auxiliary and tripping functions in control applications, remote switchgear operation, DC supply and trip‑circuit monitoring, and ferro resonance alarm.
Configure coils, contacts and indicators to your scheme, with operate and reset options. Designs resist induced AC on pilot wires and offer suppression diode options to reduce back EMF so critical circuits stay ready.
Key benefits
Mitigate downtime with continuous supervision
Detect issues in DC supplies and trip circuits early with supervision that alarms and provides clear indication, so breakers respond when needed.
Accelerate retrofits and control schemes
Use interposing relays to adapt signals and operate remote switchgear over existing pilot wires, avoiding invasive rewiring and speeding projects.
Adapt panels with flexible options
Select coils, contacts and indicator flags plus operate or reset modes to fit your exact protection scheme and maintenance practice.
