BEI EM-DR1-IC-5-TB-24V 0C Optical Isolator Module

BEI EM-DR1-IC-5-TB-24V is an optical isolator module from BEI Sensors that protects a controller from encoder-side transients by optically isolating the BEI encoder A, B, and Z signals. The device accepts encoder outputs with input voltages from 5 VDC to 24 VDC (specify the encoder voltage when ordering) and is powered by a 24 VDC supply, with open-collector outputs on each channel for straightforward interfacing to digital inputs. The packaging uses a terminal-block (TB) connection, and some distributor listings for related EM-DR1 variants note DIN-rail mounting. This module is commonly used in industrial automation to isolate encoder feedback for servo drives, PLCs, or CNC controllers while maintaining signal integrity and system isolation.
