2-channel 500 kHz encoder counter unit for CJ/NJ racks; 0.5 ms response; incremental, line-driver, and open-collector inputs.
CJ-series special I/O high-speed counter unit for CJ/NJ controllers. Supports two counters with up to 500 kHz maximum input frequency, 0.5 ms maximum response time, and multiple counter modes including simple, circular, and linear counting. Designed for incremental encoder and pulse-based motion feedback applications with screw I/O wiring and CJ I/O bus integration.

Use the dual 500 kHz counters to read A/B/Z incremental encoder signals on rotary index tables or servo feedback loops.
Reliable capture of fast pulse trains without missed counts during rapid machine motion.
Measure two independent motion axes, such as conveyor length tracking and cut-to-length positioning, using separate counter channels and pulse/direction inputs.
Accurate position tracking on two channels from one compact rack-mounted module.
Track registration marks and encoder feedback in packaging lines where fast response and rack integration are required for synchronized downstream actuation.
Maintains synchronization between product movement and machine actions at high line speeds.
