MTL4610 SWITCH/ PROXIMITY DETECTOR INTERFACE 4-channel, digital input.
The MTL4610 enables four solid-state outputs to be controlled by up to four switches or proximity detectors. Each pair of output transistors
shares a common terminal and can switch +ve or –ve polarity signals. A range of module configurations is available (see Table 1) through the
use of selector switches. When proximity detector modes are selected, LFD is enabled and the output switches to OFF if a line fault is detected.
