The Allen-Bradley 1746-HSCE2 is a high-speed counter/encoder module designed for the SLC 500 platform. This module is engineered to handle demanding industrial applications that require precise and rapid counting, position tracking, and velocity measurement. It features two independent channels, each capable of processing input signals up to 1 MHz. The 1746-HSCE2 supports a variety of counting modes, including quadrature (X1, X2, X4), pulse/direction, and up/down counting, making it highly versatile for use with encoders and other pulse-generating devices. Its user-configurable input voltage levels (5V, 12V, or 24V DC) provide flexibility for integration with a wide range of sensors and field devices, enhancing the control capabilities of any SLC 500 system.
