MTL Safety Barriers Crouse-Hinds Switch/ Proximity Detector Interface MTL4510

MTL4510 – MTL5510 SWITCH/ PROXIMITY DETECTOR INTERFACE

4-channel, digital input

The MTLx510 enables four solid-state outputs in the safe area to be controlled by up to four switches or proximity detectors located in a hazardous area. 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.
