6.1.6 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.
See page 19 for LFD and PR switch details. Channel 1 & 2 switch settings apply.
For switch sensor inputs, with LFD selected, make sure resistors (22k
Ω
and 680
Ω
) are fitted.
