Hardware and Installation Overview

• Connects thermocouples directly to two removable I/O terminal blocks.
• Each terminal block uses two screws for secure mounting on the board.
• Supports wire sizes up to #12 AWG (300V maximum rating).
• Includes a shield terminal strip on the left side for chassis grounding.
• Reduces electrical noise and improves system reliability effectively.
• Features six DC-type connectors labeled JTA, JTB, JSA, JSB, JRA, JRB.
• Three onboard LEDs indicate normal operation or fault conditions.

System Configuration and Operation

• Works with PTCC I/O packs in Mark VIe systems for 24 inputs.
• Simplex systems use two PTCC packs with the IS200TBTCH1CBB board.
• TMR applications (TBTCH1B) distribute signals to three processors.
• Each processor handles 12 thermocouple inputs in TMR setups.
• Analog-to-digital conversion and linearization occur inside the I/O processor.
• Monitors cold junction signals and uses average value for compensation.
• If a CJ fails, the system uses a backup or default configured value.

Frequently Asked Questions (FAQ)

• Is this IS200TBTCH1CBB a brand new original part?
  Yes, we supply only brand new and original GE boards. No refurbished or counterfeit items.
• Do you have this thermocouple terminal board in stock?
  Yes, we have the IS200TBTCH1CBB in stock and ready to ship.
• What is the typical lead time for shipping?
  We dispatch all orders within 5 days after payment confirmation.
• Which couriers do you use for delivery?
  We ship via FedEx, UPS, and DHL for reliable worldwide service.
• Can I return the board if it does not meet my needs?
  Yes, we support 30-day returns for a full refund, no restocking fee.
• What thermocouple types work with this board?
  This board accepts types E, J, K, S, and T thermocouples directly.
• What is the input voltage range of the IS200TBTCH1CBB?
  The input span is -8 mV to +45 mV, covering most industrial measurements.
• Does this board support TMR configurations?
  Yes, with the TBTCH1B version, but the IS200TBTCH1CBB works for simplex/dual setups.
• How does cold junction compensation work on this board?
  Two CJ reference devices provide signals; the system uses their average value.
• What happens if a cold junction sensor fails?
  The system uses a backup value from other boards or a default configured value.
