Control Relays - We design and manufacture a number of multi function Control Relays:

mains failure relay; frequency relay; load sharing relay; under voltage relay; process control relay; thermistor relay; DC under voltage monitoring; protection relay; frequency relay; battert alarm relay; current relay; voltage control relay; multi function current relays.

These Control Relays are supplied with various mountings:

The 45 series for DIN rail mounting
The M1 series either DIN rail or surface mounting
The M3 series either DIN rail or surface mounting
The 70 series either DIN rail or surface mounting
The P48 series either panel or 11 pin mounting
The B8 series with 8 pin mounting

See below for our complete range of Control Relay products.
