Detailed Product Description

MTL5510B Switch/ Proximity Detector Interface 4-Channel, Multi-function, Digital Input

MTL5510B enables four solid-state outputs in the safe area to be controlled  by up to four switches or proximity  detectors  located in 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.
