This is a versatile interface between an incremental encoder and receiving electronics. It accepts single ended or differential inputs and provides single ended or differential outputs in either an open collector or line driver configuration. It accommodates all standard operating voltages from 5 to 28 VDC. Up to eight Optical Isolator Modules can be daisy-chained to provide multiple, simultaneous outputs to controllers or PLC’s. This Optical Isolator can help clean up noisy signals by converting to a different line driver output. It has a 1 MHz throughput capability and can be used wherever a fast, optically isolated interface is required.
