MTL5526 2 channel switch operated relay isolated barrier

MTL4526 – MTL5526 SWITCH-OPERATED RELAY 2–channel IS–output The MTLx526 enables two separate IS circuits in a hazardous area to be contact controlled by one or two, on/off, control 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 IS 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.

Relay drive (see switch setting table)

Choice of "loop-powered" or "contact/logic" control, for both

channels, by switch selection. A further switch option ("1in2out")

enables either input, in contact/logic mode, to activate both

outputs.

60mA at 35V dc

Power dissipation within unit

1.1W maximum at 24V

Safety description (each channel)

Non-energy–storing apparatus: relay contacts may be connected

to any IS circuit without further consideration
