The Telemecanique LA1-DN22M is an auxiliary contact block that snaps onto the front or side of Telemecanique contactors and motor starters in the TeSys D and TeSys F families. It adds extra control-circuit contacts — normally-open and normally-closed pairs — for status feedback, interlocking, or PLC input signals, without taking up extra DIN-rail space.
The LA1-DN22M is a current-production accessory. Standard supply chain applies.
Typical deployment: wiring the normally-open contact back to a PLC digital input for motor-run status, or using the normally-closed contact in a safety interlock string. The contact block shares the same screw-clamp terminals as the base contactor, so the same wire range and tightening torque apply.
