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 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 (22kΩ and 680Ω) are fitted.
