General Description
Welcome to the Watlow Series 965, a 1/16 DIN microprocessor-based tempera-
ture control. The 965 has a single input which accepts type J, K, T, N or S
thermocouple, RTD or process input.
With dual output, the primary can be heating or cooling while the secondary can
be a control output opposite the primary output (heat or cool), alarm or none.
Both outputs can be selected as either PID or on/off. PID settings include
proportional band, reset/integral, and rate/derivative. Setting the proportional
band to zero makes the Series 965 a simple on/off control with switching
differential selectable under the HSC parameter.
Special 965 features include the NEMA 4X rating, dual four digit displays in
either red or green, optional low volt power supply, auto-tuning for both heat
and cool outputs, ramp to set point for gradual warm-up of your thermal system,
and automatic/manual capability with bumpless transfer.
Operator-friendly features include automatic LED indicators to aid in monitoring
and setup, as well as a calibration offset at the front panel. The Watlow Series
965 automatically stores all information in a non-volatile memory.
