Digital Input modules
The Digital Input (DI) module range offers solid state or relay output switches in a safe area that respond to input switches located in a hazardous area. Single or multiple channel (2 or 4) options are available, as well as Line-Fault Detection (LFD).
Modules with LFD can recognise open or short circuit conditions on the input wires going to the field sensors, and some DI modules have the facility to reverse the effect of the input on the output i.e. phase reversal.
These options are chosen with switches located on the edge of the module on the hazardous area terminal side. In some applications it may be easier to set these switches before fitting the module to the DIN-rail.
MTL5513 - switch/proximity detector interface
Two-channel, with line-fault detection and phase reversal
The MTL5513 enables two solid-state outputs in the safe area to be controlled by two switches or proximity detectors located in the hazardous area. The Ch1/Ch2 output transistors share a common terminal and can switch +ve or -ve polarity signals. Line-Fault Detect and Phase Reversal for the channel are selected by DIL switches on the side of the module. LFD indication is provided on the top of the module.
Channel 1 & 2 switch settings apply.
For switch sensor inputs, with LFD selected, make sure resistors (22kΩ and 680Ω) are fitted.
