MTL 5500 Intrinsically Safe Isolators  MTL5561

MTL4561 – MTL5561 FIRE AND SMOKE DETECTOR INTERFACE 2-channel
The MTLx561 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.
