1769-HSC - 2CH High-Speed Counter - Industrial Automation Rugged Din-Rail Module

The Allen-Bradley 1769-HSC High-Speed Counter Module delivers precision motion monitoring for Rockwell Automation's CompactLogix 5370 controllers. Engineered to process rapid digital signals from encoders, proximity sensors, and pulse generators, this modular I/O unit supports 1 MHz counting speeds with ±0.002% accuracy. Featuring a rugged, IP20-rated aluminum housing (-20°C to +70°C), it incorporates galvanic isolation (250V AC) to eliminate ground loops. Configurable via Studio 5000® software, the module integrates Quadrature Decoding for bidirectional position tracking and offers embedded PID Loop Control for real-time velocity regulation without processor load.
