MTL4510B – MTL5510B SWITCH/ PROXIMITY DETECTOR INTERFACE 4-channel, multi-function, digital input.

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.
