Allen-Bradley 1756-HSC High Speed Counter Module

Allen-Bradley 1756-HSC High Speed Counter Module is a ControlLogix I/O module designed to perform high-speed counting of fast pulses in industrial automation. The card provides two independent counter channels with four outputs (two outputs per channel) and uses a 36-pin interface to connect the input signals and drive outputs within a ControlLogix chassis, with Rockwell specifying firmware as 1756-HSC v5.011. It is intended for use with encoders and other high-speed sensors, supporting rapid event counting, rate measurement, and timing-related signaling that can feed into controller logic or trigger peripheral devices in automated processes.
