SERIES 988/989 Controllers Watlow's Series 988/989 is truly an innovation in the control field. The Series 988/989 is the first to combine so many key features into a single, 1/8 DIN size package. No other control offers the flexibility, compact size and durability of the Series 988/989. This control meets a wide variety of needs in the process industries. Its broad range of I/0 options allows control of virtually any process variable. From the long list of product features, the Series 988/989's ability to provide single unit cascade control of a process is perhaps the most unique. The Series 988/989 is the only 1/8 DIN control with this feature. Other features include heater current monitoring, remote set point input, differential or ratio control. Valve control via slidewire feedback is another popular feature. The Series 988/989 has all the standard characteristics has the auto- tuning capabilities and increased the alarm functionality. The Series 988/989 offers several unique control algorithms.

Features and Benefits: Greater application versatility with two universal analog inputs and one event input Fits easily into confined areas because of compact size (4.06 inch, [103 mm], behind panel depth) Improved control through fast 1OHz sampling rate Remote operation with serial communications, Windows Configuration Software and Modbus Precise valve control with slidewire feedback input, which controls valve position Smooth process control due to burst firing output Signal conditioner power supply eliminates need for an external device Watertight and corrosion resistance due to NEMA 4X front panel (IP65 equivalent) Watlow Series 988/989 Control

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

Features and Benefits Four files / 24 steps Designed to meet the needs of most ramping applications Auto-tuning One-step tuning of system parameters for easy operation Optional dual auxiliary outputs Flexible time-based events or alarm outputs Optional retransmit of set point or process variable For master programmer or chart recorder connection Hardware and software parameter lockout options Provides several levels of operator security NEMA 4X front panel Provides watertight corrosion resistance 10Hz sampling rate and burst-fire control Smooth, accurate control of the process Slidewire feedback Interfaces with most slidewire input positioning devices SERIES 981/982 Controllers
