Information About 1746-HSCE2
The 1746-HSCE2 is part of the SLC 500 modular platform and is designed as a multi-channel high-speed counter equipped with a dedicated onboard processor for independent signal handling. It supports single-ended and differential quadrature inputs through ±A1, ±B1, ±Z1, ±A2, ±B2, and ±Z2 channels, making it compatible with various encoder types and pulse-generating devices. With isolation between backplane and outputs, and programmable counting modes including linear, ring, and up/down, the module supports demanding industrial applications requiring precise, high-frequency measurement. The 1746-HSCE2 integrates seamlessly across SLC 500 chassis and can also function in remote I/O configurations via the 1747-ASB adapter.
Key Features
- Bidirectional high-speed counting: Supports up/down and quadrature counting for advanced position and motion monitoring.
- Multi-channel input structure: Provides six differential quadrature inputs for two encoders or four single-ended pulse devices.
- Fast input performance: Handles input frequencies up to 1 MHz with 200 ns minimum phase separation and 475 ns minimum pulse width.
- Dedicated onboard processing: Processes incoming signals independently for reliable real-time measurement and reduced PLC load.
- Isolated circuitry: Features 1000V backplane isolation and 500V channel-to-output isolation for increased system protection.
- Programmable counting modes: Supports linear, ring, and quadrature modes with ±8,388,607 (24-bit) counter capability.
- Eight configurable outputs: Includes four real 5–30 VDC sourcing outputs and four virtual outputs for flexible control logic.
- Thermal and overload protection: Equipped with rapid thermal cut-out response to protect channels during fault conditions.
The 1746-HSCE2 delivers the reliability and precision required for high-speed pulse counting and encoder-based control tasks in industrial automation.
