Banner Engineering CM3RA-D3A Maxi-Amp Sensor Module

The Banner Engineering CM3RA-D3A Maxi-Amp Sensor Module is a MAXI-AMP CM Series amplifier module that interfaces Banner remote sensors with control equipment. It accepts power from 105 to 130 V ac or 12 to 28 V dc and provides two outputs: an SPDT electro-mechanical relay and a complementary NPN transistor solid-state DC switch, enabling both load control and logic-level signaling from a single module. Designed to minimize optical cross-talk among adjacent sensors, the CM3RA is built for robust industrial use with Banner’s modulated remote sensors, offering a compact, integrated solution for signaling, interlocking, and automation tasks in control panels. This module is ideal for applications where a single device must drive a relay load while also supplying a DC-switch output to PLCs or other digital inputs, simplifying wiring and improving reliability in automation systems.
