The Watlow Series 965 Microprocessor-Based Auto-Tuning Controller is a dual output, single input, microprocessor-based, 1/8 DIN, auto-tuning temperature control, featuring the Automatic/Manual capability with bumpless transfer. In the Auto mode, the control has closed loop control with sensory feedback, while the Manual mode has open loop control with user defined output power level. The 980/985 accepts a Type J, K, T, N, or Platinel2 thermocouple, RTD, or process input. The primary output is Heating or Cooling, while the secondary output can be Heat, Cool or Alarm.
