The Watlow F4SH-KAA0-01RG is a 1/4 DIN single-channel ramping temperature controller engineered for precision thermal management in semiconductor manufacturing, plastics processing, and industrial process control. Built around a 16-bit microprocessor, it delivers ±0.1% of span accuracy with a four-line LCD interface for configuration and real-time monitoring. The controller supports up to 256 programming steps across 40 nameable profiles with six step types including ramp, soak, and jump functions. Universal sensor inputs accept 100 Ohm RTD (DIN and JIS curves) and thermocouple signals.
