1746-HSRV AB
The AB 1746-HSRV is a high-speed counter module manufactured by Allen-Bradley. It is designed to accurately count and measure high-speed events and pulses in industrial applications.
The module features four counter channels with a maximum counting frequency of 1 MHz. It supports pulse widths as small as 50 nanoseconds, allowing for precise measurement of quick events. Each counter channel has an input and an output terminal, providing flexibility for various input and output configurations.
The 1746-HSRV module has a high noise immunity, ensuring reliable operation even in noisy environments. It also includes a diagnostic LED indicator, which aids in troubleshooting and monitoring the module’s status.
This module is compatible with the Allen-Bradley SLC 500 programmable logic controllers (PLCs) and can be easily integrated into existing control systems. It supports multiple programming languages, including ladder logic, function block diagram (FBD), and structured text (ST), allowing for flexibility in programming and application development.
