Auto-Tuning PIDControllers

SD_C

The features and performanceoffered by SERIES SD_C controllers make them ideally suited for a broad range of applications in temperature and process control. The SERIES SD_C controllersinclude a universal sensor input with up to three outputs that can be programmed for heat or cool temp- erature control or to operate as process or deviation alarms. Programming inverse scaling is also simplified with the user-friendly set- up menu, providing additional value without additional cost. Advanced features of SERIES SD_Ccontrollers include EIA-485 Modbus™ serial communications, Watlow’s INFOSENSE™ sensor technology, infrared remote communications operation, Watlow’s patented UserDefinable Menu System and a “Saveand Restore” feature that allows the restoration of either factory or user- defined settings.Available in
