Bulletin 900 Controllers with Enhanced Features
Both the hardware and function set of the Bulletin 900-TC8 and 900-TC16 temperature controller product lines offer an enhanced feature set
as compared to the 900-TC32. The controller enhancements allow the Bulletin 900-TC8 and 900-TC16 line a much wider range of process
applications. Key enhancements include:
ModBus is a registered trademark of Group Schneider.
• Analog voltage and current inputs
• The combination of thermocouple and platinum RTD controller types into one Global Temperature (GT) controller which incorporates both sensor input types
• A second voltage (SSR) or Triac (electronic relay) control output without loss of an alarm output
• 0...20 mA analog output in addition to the existing 4...20 mA output
• Analog transfer output function to allow easy connection to a strip chart recorder or PLC input
• Manual control of the output from the controller keypad, with bumpless transfer to the Automatic PID mode
• 11-segment alphanumeric LED readouts to display the controller parameters in a more understandable format
• Single- and three-phase heater burnout and short circuit detection
• Faster sampling rate to 250 ms
• Direct connection to your PC's USB port and 4-pin serial port on the controller using the 900-CPOEM1 cable. Allows 1-to-1 (non-network) parameter
configuration and monitoring without the need of an option communication unit/module.
• ModBus
