The two control modes are co-resident and may be selected through factory or field configuration. The 2208e features modular hardware, two control outputs, two digital inputs, self-tuning, a simple ramp-dwell setpoint programming feature and optional relay alarms and communications port. The control outputs may be configured for heat/alarm, heat/cool or for valve open/close Precise Control Advanced PID or valve positioning algorithms give stable straight-line control of the process. A power feedback feature automatically compensates the output to stabilize the temperature of electrically heated loads during supply voltage fluctuations. Proprietary cooling algorithms ensure optimum control of fan, oil and water-cooled systems. Velocity mode valve control algorithms allow precise valve UL and cUL pending control without depending on vulnerable valve position slidewire feedback. Universal Input A universal input circuit with an advanced A-D converter samples the input at 9Hz and continuously corrects it for drift, giving high stability and rapid response to process changes. A filtered input covers all thermocouple types, Pt100 3-wire RTD and linear inputs. The patented Instant Accuracy™ feature allows precise input measurement and control to be achieved from the moment of start up, independent of warm-up drift, and even during periods of ambient temperature upset. Easy Operation Bright, clear front-panel LED’s display the process variable and a configurable lower display for setpoint or other important parameters. Tactile pushbuttons ensure positive operation. All instrument parameters are easy to access and may be presented to the operator or hidden from view under password protection. A Siebe Group Company 2208e Temperature Controller 2208e Controller PhaseII 8/31/98 11:10 AM Page 2 Patented PDSIO® Load Diagnostics PDSIO® (Pulse Density Signaling Input/Output) is a patented innovation in the 2208e. When used in combination with the Eurotherm TE10S Solid State Contactor, the same wires from the 2208e that transmit the logic output to the SSC can be used to read back load faults, SSC status and load RMS on-current. SSC failure (open or short circuit) or load failure (fuse blown, heater open circuit, missing line voltage) alarms can be detected, flash on the front panel and trip alarm relays. Amperage information can be read, displayed, and alarmed. PDSIO® information is also available on serial communications. PDSIO® is not available on the Valve Positioner. Alarms Up to four process alarms may be combined to a single alarm output. Alarms may be full scale high or low, deviation, rate of change or PDSIO® load failure. Alarms may be latching or non-latching and will flash on the front panel. Blocking alarms, which only become enabled after first entering a safe state, are also available. Digital Communications EIA-485 2-wire, EIA-422 4-wire or EIA-232 serial communications is optionally available with industry standard Modbus® or proprietary EI-Bisynch protocol.
