W A T L O WTemperatureControllersSERIES D8The Watlow SERIES D8 isa powerful line of controllers that<strong>com</strong>bines performance and flexibilitywith <strong>com</strong>pact design. Compliancewith the ODVA and SemiconductorSIG standards means this controlleris easy to integrate into systems withDeviceNet networks on CAN(Controller Area Network).The four and eight loop versions ofSERIES D8 controllers provide<strong>com</strong>plete control solutions for abroad range of applications.Support for multiple types of sensorinputs including thermocouples,RTDs, linear voltage and currentis also available.Each loop can be individuallyconfigured for on-off control or PIDcontrol. Loops can be <strong>com</strong>bined toachieve cascade, ratio or differentialcontrol. Process variable retransmitand remote analog set point areincluded.The SERIES D8 controllers are UL ®and C-UL ® listed, meet therequirements of the EuropeanCommunity EMC Directive and carrythe CE mark.Features and BenefitsPID control of up to eight loops• Minimal panel space per loop• Reduced installation time• More reliable: fewer parts meanfewer failuresComplies with ODVA (OpenDeviceNet Vendors Association)and Semiconductor SIG (SpecialInterest Group) specifications forDeviceNet on CAN (ControllerArea Network)• Integrates with other DeviceNetnodes and software• Sealed micro connector minimizesinstallation time and footprint whilemaximizing reliability• Rotary baud rate and nodeaddress switches simplify setup• Network and module status LEDssimplify <strong>com</strong>missioning andtroubleshooting a networkFlexible, easy-to-use interface• Easy set up with menu guided,full-text prompts• Context-sensitive, on-screen helpsaves timeAdvanced control utilities• Auto-tune optimizes control withminimal effort and expertise• Cascade minimizes overshootand improves control in systemswith excessive thermal lag• Ratio and differential enhancecontrol in areas where therelationship between two or moreloops is paramountSpecificationsOperator Interface• 32-character vacuum fluorescentdisplay• Eight-key keypad to accessguided menus and prompts, setvalues and view channel displays• Built-in context sensitive helpNoise Rejection• 120dB at 60HzTemperature Coefficient• 40ppm/˚CAnalog Inputs• Thermocouples: User selectabletype, direct connection,linearization, reference junction<strong>com</strong>pensation, reversed andshorted T/C detection andupscale break protection withoutput averaging• RTD: 2- or 3-wire, platinum,100Ω @ 0˚C, DIN-curve.
