Banner Engineering MA4L Micro Amp Logic Module

The Banner MA4L MICRO-AMP latch logic module accepts 10–30 V DC supply and draws under 20 mA (excluding load), enabling direct use with other MICRO-AMP amplifiers or the NPN outputs of self-contained DC sensors. It provides two open-collector NPN outputs with complementary polarity (one normally open, one normally closed) that can sink up to 150 mA each, with a saturation voltage under 0.5 V at 10 mA. The device supports latch and edge-triggered modes; inputs are INPUT, INHIBIT, SET, and RESET and are buffered for about 1 millisecond, with a selector to set input polarity (fully clockwise for high-going transitions; fully counterclockwise for low-going transitions); a red LED atop the module indicates when the normally-open output is conducting. Construction is a totally encapsulated plug-in package in VALOX housing with gold-flashed pins, and it operates from 0 to 70 C with reverse-voltage protection. Note: Banner lists MA4L as obsolete in its MICRO-AMP catalog, with replacement guidance available.
