Key features of the 1794-VHSC module include:

High-Speed Counting: The module supports high-speed input signals for applications such as counting pulses, measuring rotational speed, and monitoring position.

Input Channels: It typically provides four independent input channels, each capable of handling high-speed digital input signals.

Counting Modes: The module supports various counting modes, including pulse and quadrature counting. Pulse counting mode counts each input transition as a single increment, while quadrature counting mode counts the number of cycles and direction based on two-phase signals.

Input Filtering: The module includes configurable input filtering options to reduce noise and improve signal integrity.

Communication Protocol: The 1794-VHSC module interfaces with the control system or PLC via a communication network, typically using an RS-232, RS-485, or other industrial protocols.
