Watlow STKL-F2MG-BAAA Solid State Temperature Controller

The Watlow STKL-F2MG-BAAA EZ-ZONE ST solid-state temperature controller provides integrated PID temperature regulation and solid-state load switching for industrial heating and process-control systems, with DIN-rail mounting for easy panel integration. It operates on 110/120 VAC (50/60 Hz) and accepts a universal input with sensor compatibility for thermocouples, RTDs, or other process inputs, and is commonly used in industrial ovens, plastics processing equipment, packaging machinery, and process heating systems. Output features include a zero-cross SSR output of 25A at 48–600 VAC, an auxiliary SSR output of 0.5 A, a 5 A Form C limit relay, a 2 A Form A relay, and a 2-pole 40 A contactor, along with isolated EIA-485 Modbus RTU communication. Protective measures include overtemperature and undertemperature protection, and the unit carries UL, CSA, CE, FM, and RoHS certifications.
