Information About 1794-VHSC
The 1794-VHSC is part of the Allen-Bradley FLEX I/O family, designed to provide high-speed counting functions within distributed I/O architectures. Offering two independent channels, the module captures pulses from encoders, proximity sensors, mechanical switches, and other fast-acting devices with frequencies up to 1 MHz. Its compact, open-style FLEX I/O design integrates seamlessly with controller platforms such as CompactLogix and ControlLogix when paired with compatible adapters. Built for in-cabinet applications, the module simplifies high-speed signal processing where rapid feedback, precise positioning, or real-time counting is required.
Key Features:
- Dual 1 MHz counting channels: enables precise capture of high-frequency pulses from encoders, pulse wheels, and other fast-acting devices in motion systems.
- Versatile 5 VDC or 24 VDC input support: accommodates a wide range of industrial sensors including proximity switches, mechanical contacts, and digital pulse sources.
- Integrated frequency and count modes: outputs either raw counts or frequency data in binary format for flexible control strategies in automation tasks.
- Two digital output channels: provide real-time event signaling or control actions based on preset count thresholds or speed conditions.
- FLEX I/O modular design: supports distributed I/O architectures with space-efficient mounting and simple integration using compatible FLEX adapters.
- High-speed screw-terminal connections: ensure reliable wiring for fast signal transmission and secure termination of encoder and sensor lines.
- IP20 open-style construction: suited for protected cabinet environments where compact, high-density I/O is required.
- Certified for global industrial use: meets CE, KC, Marine, and other standards for broad deployment across varied industries.
The 1794-VHSC delivers the reliability and precision required for high-resolution counting, motion feedback, and fast digital signal processing in advanced automation systems.
