SPECIFICATIONS

Part No.: IS230TBTCH1B
Manufacturer: General Electric
Product Type: Thermocouple Input terminal board
Country of Manufacture: United States (USA)
Series: Mark VIe

IS230TBTCH1B is a thermocouple input terminal board developed by GE. It is a part of Mark VIe control system. The Thermocouple Input terminal board accepts thermocouple inputs of 24-type E, J, K, S, or T. It only accepts additional B, N, and R thermocouple inputs when used with the PTCCH2 in the Mark VIe control system. These inputs are connected to two barrier-type terminal blocks. Through DC-type connectors, TBTC communicates with the I/O processor.

Compatibility

  • TBTC works with the PTCC I/O pack in the Mark VIe system and supports simplex, dual, and TMR applications.
  • Two PTCC packs plug into the TBTCH1C for a total of 24 inputs in simplex systems. The TBTCH1B can connect one, two, or three PTCC packs, allowing for a variety of system configurations.

Installation

  • Connect the thermocouple wires to the two I/O terminal blocks directly. These removable blocks are attached to the terminal board with two screws.
  • Each block has 24 terminals that accept wires up to #12 AWG. On the left side of each terminal block is a shield terminal strip connected to chassis ground.
  • Connect the I/O packs to the TBTC J-type connectors directly. The number of cables or I/O packs depends on the level of redundancy required.

Product Attributes

  • Number of channels: 24 channels per terminal board
  • Cold junction temperature accuracy: CJ accuracy 1.1 degrees Celsius.
  • Span: -8 mV to +45 mV if TBTC is connected to PTCCH1 / VTCCH1, -20 mV to +95 mV if TBTC is connected to PTCCH2 / VTCCH2

Thermocouple Limits

  • Full-scale input ranges are supported by thermocouple inputs. The tables below show typical input voltages for various thermocouple types versus the minimum and maximum temperature ranges.
  • Temperature ranges for cold junctions (CJs) are assumed to be between -30 and 65 degrees Celsius.
