Description

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

 

Ramping operations include four files with six steps in each file. 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 primary analog input accepts 11 different thermocouple types, RTD or scalable process inputs. A second analog input can be factory configured for a slidewire feedback input common in gas valve control. With up to two event inputs, the Series 981/982 offers remote program start or hold capability and allows the operator to program a wait-for event.

 

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

 

The Series 981/982 features a three-year warranty and four day shipment, on all model, in limited quantities.
