MTL5514 – Switch/Proximity detector interface
Single channel, with line-fault detection and phase reversal
The MTL5514 enables a safe-area load to be controlled, through a relay, by a proximity detector or switch located in a hazardous area. Line faults are signalled through a separate relay and indicated on the top of the module. The MTL5514D provides signal duplication, enabling two safe-area loads to be controlled by a single device in a hazardous area. Both relay outputs reflect the input signal instead of one showing the line fault condition as in the MTL5514. 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 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 relays should be not less than 50mW, e.g. 10mA at 5V DC.
