Industrial Application Scenarios

The DO561 (1TNE968902R2201) module is widely deployed in highly localized automation machinery, small HVAC ventilation arrays, pumping skids, and embedded control cabinets where panel depth and width are strictly limited. Due to its slim 34 mm hardware footprint, it allows machine builders to effortlessly expand the output capabilities of an AC500-eCo processor. It safely triggers low-draw control equipment such as miniature control relays, small pneumatic valve manifolds, status indicator lamps, and acoustic alarm buzzers.
