Relays

M200 Relays
 
The M200 series is a comprehensive range of AC and DC Monitoring Relays. The relays provide continuous monitoring of electrical systems. Customer adjustable trip points, time delays and resets are available depending on relay type.
The M200 series has U.L. Approval and Isolation of 4kV.
 
M220 MultiThin Relays
 
The M220 series is a new range of slimline monitoring relays. The relays provide continuous monitoring of electrical systems. Customer adjustable trip points, time delays and resets are available depending on relay type.
 
M570 PowerRelay
 
The M570 PowerRelay is a complete single phase or three phase multifunction, RMS sensing, AC power transducer, providing up to 3 set point relay outputs, one energy relay and an RS485 communication port. Several of the parameters measured by PowerRelay can be assigned to the set point relays (marked ** below)
The M570 is fully programmable through the communication port.
Up to 3 fully isolated relay outputs are available.
Most of the parameters measured can be assigned to the relays.(marked **)
An optional pulsed output via a relay is offered.
It can be assigned to W.h, Var.h (import or export), A.h or VA.h.
