The MTL5511 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 line-fault-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.

User-selectable via switches on the side of the unit. A line fault is
indicated by an LED. The channel output relay is de-energised if
an input line fault is detected.
Open-circuit alarm on if Iin < 50μA
Open-circuit alarm off if Iin > 250μA
Short-circuit alarm on if Rin < 100Ω
Short-circuit alarm off if Rin > 360Ω
