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.
The MTL3012 can be used in some flowmeter applications. The frequency response of dc to 2kHz and its ability to accept proximity
type inputs make it ideal for positive displacement (PD) meters and some turbine meters.
