Multi-Period Totalizers are advanced devices designed to capture and display counts from various sensors such as potential-free contacts, NPN, or PNP sensors. These totalizers are ideal for applications requiring real-time, periodic, and cumulative counting, featuring multiple displays for parameters like current hour, previous hour, day totals, and seasonal totals.

The totalizers are available in three models (WSM21, WSM86, and WSM22D), each catering to different display size and functionality requirements. These models provide precision counting and are easy to integrate into industrial environments.
