MTL4526 safety isolators 2 channel switch operated relay England origin product
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.
