Switch Promity Detector Interface Two single-pole relays with changeover contacts, Digital Input, Line Fault Detection (LFD), Phase Reversal, Contact Rating Safe Area 250Vac 2.0A / 40Vdc 2.0A Contact Rating Zone 2: 35VDC, 100VA, 2.0A, c/w AC Power AdaptorDin Mount

Features:
• The MTL5516/C enable two safe-area loads to be controlled by a switch or proximity detector located in a hazardous-area.
• When selected, open or short circuit conditions in the field wiring are detected by the line fault-detect (LFD) facility and also indicated on the top of the module.
• Phase reversal for each channel is selected by a switch on the side of the module and output is provided by changeover relay contacts.
• The MPA5500 enables any MTL5500 module that is normally powered from a nominal 24V DC supply (i.e. those that are not loop-powered) to be powered from a high-voltage AC supply.
• It plugs into the power socket (terminals 13 and 14) of an MTL5500 module and clips securely onto the module housing. The 25V DC power output from the adaptor is sufficient to supply a single module and can be connected to any normal AC power source.
