The vertical 1/8 DIN Watlow Series 982 ramping temperature controller and its companion, the horizontal Watlow Series 981 ramping temperature controller, offer four-file / 24-step program capability or easy-to-use non-ramping setpoint operation. Designed with most typical programming needs in mind, the Watlow Series 981 / 982 ramping temperature controller is among the most easy-to-use ramping controllers.

Ramping operations include four files with six steps in each file. The Watlow Series 981 / 982 ramping temperature controller's programming options include ramp-rate or time-based profiles, guaranteed soak deviation, program looping, and program status selection after power outage. The files may be linked to create a single 24-step program.

The Watlow Series 981 / 982 ramping temperature controller's primary analog input accepts 11 different thermocouple types, RTD or scalable process inputs. A second analog input can be factory configured for slidewire feedback input common in gas valve control. With up to two event inputs, the Watlow Series 981/982 ramping temperature controller offers remote program start or hold capability and allows the operator to program a wait-for event.

The Watlow Series 981 / 982 ramping temperature controller is packaged with a NEMA 4X front panel to withstand harsh environments, a four inch case depth, and touch-safe wiring terminal.
