MTL

The MTL2213 enables three 100VA safe-area loads to be controlled independently by three light-duty on/off switches or certified proximity detectors in a hazardous area. Switches and proximity detectors may be mixed. The three input circuits are interconnected but fully floating. For proximity-detector and some switch applications, a phase-reverse link allows alarm conditions to be signalled for either state of the sensors. ‘Alarm’ means relays de-energised with their on/off contacts open, and all three circuits have to operate in the same fashion. This compact low-cost unit is suitable for a wide variety of applications. The MTL2213 supersedes the MTL2212 for which it is a direct replacement, except that only terminal 8 can be used for connecting to earth.
