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. Independent output
phase reversal and line fault detection are enabled via switches for
each output. LFD indication is provided on the top of the module.

Hysteresis: 200µA (650Ω) nominal
Line fault detection (LFD) (when selected)
User-selectable for each channel via switches on the side of the
unit. Line faults are indicated by an LED for each channel.
