W A T L O WTemperatureControllersFor <strong>com</strong>plete information onSERIES SD controllers referencepages 174 to 178.SERIES SDThe features and performanceoffered by Watlow’s family of SERIESSD PID controllers make them ideallysuited for a broad range ofapplications in temperature andprocess control.Watlow’s SERIES SD single channelcontrollers include a universalsensor input with up to three outputsthat can be programmed for heat orcool temperature control, or tooperate as process or deviationalarms. Programming InverseScaling is also simplified with theuser-friendly set-up menu, providingadditional value without additionalcost.Advanced features of SERIES SDcontrollers include EIA-485Modbus Serial Communications,Watlow’s INFOSENSE sensortechnology, Infrared RemoteCommunications operation, Watlow’spatented User Definable MenuSystem and a "Save and Restore"feature that allows the restoration ofeither factory or user-definedsettings. Two non-linear PID curveshave also been added to improveperformance in plastics extruderapplications.Available in 1 ⁄32, 1 ⁄16, 1 ⁄8 and 1 ⁄4 DIN panelmount sizes, Watlow’s SERIES SDfamily is backed by an industryleading three-year warranty fromWatlow. The SERIES SD controllersare UL ® and C-UL ® listed, CSA, CEand NSF-2 certified and include theIP65/NEMA 4X seal.SERIES SD6_DThe SERIES SD6_D has beensuccessfully tested for use withODVA for DeviceNet on CANnetworks. The controller includes auniversal sensor input with twooutputs that can be configured asheat, cool or alarm. The DeviceNet<strong>com</strong>munications interface issupplied with a five-positionremovable screw terminal connector.For more information on the SERIESSD6_D controller, turn to page 175.SERIES SD31The SERIES SD31 offers improvedaccuracy of 0.1 percent of span aswell as a faster sampling rate of6.5Hz in a 1 ⁄32 DIN package. Userscan also select between 11 differentthermocouples, a 100 Ohm RTD, a0 to 20mA or 0 to 10V process inputallfrom the front panel- thateliminates the need for dip-switches.For more information on the SERIESSD31 controller, turn to page 177.Features and BenefitsWatlow’s INFOSENSE sensortechnology• Thermal sensing technologyimproves sensor accuracy by aminimum of 50 percentWatlow’s patented User DefinedMenu System• Allows the user to assign up to 20parameters in the operations menu• Improves operational efficiency“Save and Restore” feature foruser settings• Allows the user to save individualor factory settings• Eliminates the need to contact theOEM or factory to restore settingsWATVIEW HMI (Human MachineInterface)• Permits operation, configurationand data logging via a standardWindows ® PCInfrared <strong>com</strong>munications• Allows easier controller setup,operation and monitoringUp to three outputs (two for 1 ⁄32 DIN)• Results in application versatilityDual display on all models• Provides better recognition ofprocess changesRamp to set point• Controls temperature riseVariable burst fire• Prolongs heater lifeThermoformingTemperature ControllersDeviceNet is a registered trademark of the OpenDeviceNet Vendors Association.341
