BEI EM-DR1-IC-5-TB-28V Optical-Isolator Module

The BEI Sensors EM-DR1-IC-5-TB-28V Optical-Isolator Module provides galvanic isolation for encoder signals, protecting controllers from voltage transients and electrical noise while preserving pulse integrity. It accepts encoder outputs A, B, Z on the input side and is powered from 5 to 28 V, with isolated outputs on the A/, B/, and Z/ lines feeding the controller. The three output configurations correspond to EM-DR1-IC-5-TB-28V/V, EM-DR1-IC-5-TB-28V/5, and EM-DR1-IC-5-TB-28V/OC, delivering Vout = Vin, Vout = 5 V, or Vout = OC respectively. Packaged as a terminal-block (TB) module, it is designed for straightforward wiring in BEI encoder systems. Distributor and factory references such as 60001-003 (internal BEI documentation) and cross-refs like 924-60001-003 help sourcing, while BEI encoders and related interface circuitry are the intended pairing. Typical applications include interfacing BEI encoders to CNC machines, robotics, servo drives, and other motion-control controllers where isolated, reliable signal transfer is required.
