Allen-Bradley 1734-VHSC5 Very High Speed Counter IO Module

Allen-Bradley 1734-VHSC5 Very High Speed Counter Module is a 1-channel POINT I/O module designed for ultra-fast counting of digital events and encoder-based position/velocity tasks. It accepts 5V DC input signals on its single input channel and is powered by the POINT I/O backplane (the 5V version does not require a separate power bus). The module supports encoder modes X1, X2, and X4 with speeds defined by the chosen mode, enabling high-frequency counting suitable for high-speed packaging lines and other demanding applications. On the output side, the VHSC5 provides an isolated output group that can be used for timed outputs and PWM generation, with configuration words allowing the output to be tied to multiple compare windows and to control the PWM period and duty behavior. Configuration words govern counter preset, rollover behavior, and safe-state values, while additional words enable ON/OFF windows for the counter; as part of Rockwell's POINT I/O Series C, this module is designed for integration with other POINT I/O modules in automation tasks that require precise high-speed counting and output control.
