توضحات محصول
The MTL4511 enables a safe-area load 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 linefault-detect (LFD) facility and also indicated on the top of the module. Phase reversal for the channel is selected by a switch on the side of the module and output is provided by changeover relay contacts
