6.1.4 MTL4513 - Switch/Proximity detector interface
Two-channel, with line fault detection and phase reversal
The MTL4513 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 Section 5.1.1 on page 8 for LFD and PR switch details.
Channel 1 & 2

apply.
For switch sensor inputs, with LFD selected, make sure resistors (22k
Ω
and 680
Ω
) are fi tted.
Note
: Signal plug HAZ1-3 is required for access to the earth leakage detector function.
