                                 MTL 4500 Intrinsically Safe Isolators  MTL4561

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.

                                        



MTL4561 safe isolator product specification

The MTL4500 range is the latest generation of backplane mounting products, building upon the heritage of MTL4000 and introducing many key application benefits.
