MTL Safety Barriers Crouse-Hinds Switch/ Proximity Detector Interface MTL4510B

MTL4510B – MTL5510B SWITCH/ PROXIMITY DETECTOR INTERFACE

4-channel, multi-function, digital input

The  MTL4510B  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. These include start/stop operations and pulse output modes.
