MTL5511 – Switch/Proximity detector interface
Single channel, with line-fault detection
MTL5511 contains a changeover relay, which enables a safe-area load to be controlled by a switch or proximity detector located in a hazardous-area. When selected, the line-fault detect (LFD) facility detects open or short circuit conditions in the field wiring and also indicates this on the top of the module. Line-Fault Detect and Phase Reversal for the channel are selected by DIL
switches on the side of the module and output is provided by the changeover relay contacts.
For switch sensor inputs, with LFD selected, make sure resistors (22kΩ and 680Ω) are fitted.
Note: For reliable, long-term operation the load on the output switching relay should be not less than 50mW, e.g. 10mA at 5V DC.
