The ST-6214 / 9106 NN3 control transformer supplies 100 VA of isolated 24 VAC power from a 24 VAC primary to a matching secondary, operating at 50/60 Hz in industrial control circuits. It mounts on chassis or panels and uses a laminated core construction for galvanic isolation between primary and secondary windings. Technicians install this transformer in PLC panels, machine tools, HVAC equipment, packaging machinery, and OEM control cabinets to power relays, contactors, and auxiliary devices while maintaining electrical separation.
