EPS5516C-2 Hazardous area Safe area MTL5516C SWITCH/ 1 2 PROXIMITY DETECTOR &( INTERFACE & * ( two-channel, with line fault detection ) &( * The MTL5516C enables 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.
