Baumer G220A03 Rotary Counter Timer 25 Pin Type

Baumer G220A03 Rotary Counter Timer is an industrial counter/timer module that records six counts per shaft rotation and uses a 25-pin type interface. In catalogs, it is listed as G-220.A03 and traces to Baumer Electric's IRION & VOSSELER timer/counter lineage. The unit is designed to monitor rotary movement in automation systems by counting rotation events—each full turn yields six increments, enabling simple inference of speed or rotation frequency when paired with an appropriate sensor or encoder and compatible control hardware. The 25-pin interface provides the electrical connections required to integrate this counter into legacy Baumer-based installations or retrofit projects where a dedicated rotary count function is needed. As a dedicated hardware counter/timer, the G220A03 serves applications that require hardware-level counting of rotary events without software polling, a common arrangement in industrial control panels and machine interfaces. The G220A03 designation appears in distributor catalogs and second-hand listings, reflecting the model’s enduring reference in Baumer’s legacy product family.
