Bulletin 900-TC

Single-Loop Temperature/Process Controller

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

RTU (master/slave) protocol

Version 1.2 of 900BuilderLite is required to configure Series B controllers if the software configuration option is used versus the controller keypad. NOTE:

Version 1.1 saved parameter cannot be downloaded using Version 1.2

7 Requires the use of a communication option unit: 900-TC8232 (Series B) for RS232C or 900-TC8COM (Series B) for RS485 communications.

‡ Requires the use of a Series B RS485 communication option unit: Refer to Table “Option Units”. NOTE: Series A option units cannot be used with Series B

controllers and vice versa.

§ Requires the use of an event Input option unit: 900-TC8EIM (Series B)

♣ Requires the use of a Series B Event Input option unit: Refer to Table “Option Units”. NOTE: Series A option units cannot be used with Series B controllers and

vice versa.

Yes
