Product Description
The Allen-Bradley 1746-HSCE2 is a high-speed counter module from the SLC 500 family (Bulletin 1746), designed to handle precise counting, position tracking, and rate measurement independently of the processor scan cycle. By offloading counting tasks from the CPU, it ensures deterministic performance even at very high input frequencies.
This specialty I/O module supports four independent channels with single-ended or differential quadrature encoder inputs and can process pulse frequencies up to 1 MHz. It also features two fast analog inputs and two analog voltage outputs, making it versatile for advanced automation and motion control applications. The module is ideal for packaging, material handling, robotics, and process automation systems where high-speed counting is critical.
Although discontinued by the manufacturer, the 1746-HSCE2 remains supported with a Radwell 2-year warranty, making it an excellent option for maintaining and upgrading legacy SLC 500 systems.
