Description

MTL5526 Switch Operated Relay

The MTL5526 enables two separate IS circuits in a hazardous area to be relay-contact controlled by two on-off switches or logic signals in a safe area. Applications include the calibration of strain-gauge bridges: changing the polarity (and thereby the tone) of an IS sounder; the testing of I fire alarms; and the transfer of safe-area signals into an annunciator with IS input terminals not segregated from each other. The output-relay contacts are certified as non-energy-storing apparatus and can be connected to any IS circuit without further certification provided that separate IS circuits are such that they would remain safe if connected together.
