MTL5510 (4-channel, digital input)
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. When proximity detector modes are selected, LFD is enabled and the output switches to OFF if a line fault is detected.
