Available. The Allen-Bradley 1746-HSCE is a high-speed counter module designed for the SLC 500 series programmable logic controllers (PLCs). This single-channel module is engineered to handle high-speed counting applications, making it ideal for tasks such as motion detection, totalizing, and processing high-speed discrete inputs. It supports various input types, including quadrature (A/B/Z), pulse/direction, and up/down signals, with input voltages of 5V DC, 12V DC, or 24V DC. The module offers multiple operating modes, including range, rate, and sequencer functions, providing flexibility in automation applications. It features four open-collector outputs and operates within an ambient temperature range of 0°C to 60°C (32°F to 140°F). The 1746-HSCE is compatible with SLC 5/02 and higher processors, ensuring seamless integration into existing systems.
