MTL5561 Galvanic Isolator
The MTL5561 is a loop-powered 2–channel interface for use with conventional fire and smoke detectors located in hazardous areas. In operation, the triggering of a detector causes a corresponding change in the safe–area current. The unit features reverse input polarity protection, while ‘no-fail’ earth fault detection on either line can be provided by connecting an earth leakage detector to terminal 3 and/or 6.
