MTL3011 AND 3012 SWITCH /PROXIMITY DETECTOR RELAYS

MTL3011 – volt-free contacts MTL3012 – solid state

These basically similar units both enable a safe-area load to be controlled by a proximity detector or switch located in a hazardous

area, the MTL3011 having a relay output for general use, and the MTL3012 a floating solid-state on/off switch compatible with logic

circuits. In both units a built-in phase-reverse control allows an alarm condition (output open) to be signalled for either state of the sensor. A line-fault detection feature opens the output in the event of short or open-circuit lines: intended for use primarily with proximity detectors, it can also be used with switches made to resemble them electrically by adding two resistors, or disabled by a link if not required.
