GE Fanuc IC655APU510 High Speed Counter Module

Product Overview

The IC655APU510 is a GE Fanuc high-speed counter module for the Series Five PLC. It processes rapid pulse signals used to track variables such as position, speed and flow. Its two count input channels accept up/down pulse signals or signals from an A-quad-B incremental encoder.
The module counts at up to 50 kHz and supports preset and ring counting modes. When a preset value is reached, its open-collector output can respond without waiting for the Series Five CPU to process the event. This makes the IC655APU510 useful where a pulse count must trigger a timely control response.
