More Information

Overview Manuals Thermocouple Channels Field Termination VTCC Signal Path Diagnostics & Setup

Features:

  • IS210DTTCH1A terminates twelve thermocouple channels for one VTCC cable path.
  • Two boards can supply a single VTCC with 24 temperature inputs.
  • Cold-junction sensing, open-circuit checks, and board identification share the assembly.
The 42-position block on IS210DTTCH1A separates thermocouple conductors, shield screws, and the two SCOM points.

VTCC excites the cold-junction circuit and receives the twelve channels plus identification data from IS210DTTCH1A.

IS210DTTCH1A is a simplex board and is not the terminal assembly used with PTCC.

The General Electric IS210DTTCH1A Mark VI Thermocouple Terminal Board is listed by Apter Power with product documentation and matching support.

Twelve Temperature Inputs

  • Channel count: Twelve thermocouple circuits terminate on each DTTC board.
  • Processing link: One 37-pin cable carries the channel set to VTCC.
  • Expanded count: Two DTTC boards give one VTCC a total of 24 inputs.
  • Cold junction: The board includes a local reference with 1.1 °C accuracy.

 Permanent Euro-Block

  • Terminal positions: The high-density block provides 42 screw connections.
  • Shield pattern: Every third screw is reserved for cable shielding.
  • SCOM: Terminals 41 and 42 provide the board ground connections.
  • Board format: The terminal block is fixed to the compact DIN-rail assembly.

Signals Returned Through JA1

  • Measurements: Twelve thermocouple signals travel to VTCC.
  • Reference: VTCC excites the cold-junction circuit and receives its measured value.
  • Identification: Board ID data shares the cable path.
  • Conditioning: Front-end circuits match the TBTC signal-conditioning arrangement.

Input Supervision

  • Limit checks: Hardware high and low thresholds monitor each channel.
  • Open circuit: Injection circuitry supports detection of a broken thermocouple path.
  • ID check: VTCC can report a terminal-board mismatch.
  • Hardware setup: No jumpers or switches require adjustment.
Description
General Electric IS210DTTCH1A is a compact DIN-rail thermocouple terminal board for simplex Mark VI temperature acquisition. Twelve thermocouple channels terminate on the board and pass through a single 37-pin cable to a VTCC thermocouple processor.

A fixed 42-position Euro-style terminal block organizes field wiring on IS210DTTCH1A. Every third screw is assigned to cable shielding, terminals 41 and 42 provide SCOM connections, and the signal conditioning and cold-junction reference follow the same circuit arrangement used by the larger TBTC board.

Two IS210DTTCH1A boards can connect to one VTCC for a total of 24 inputs. The cold-junction reference excitation comes from VTCC, while the twelve thermocouple signals, the cold-junction value, and board-identification data return through the JA1 cable path.

Channel monitoring on IS210DTTCH1A includes hardware high and low limit checks, open-circuit injection, and board-identification mismatch detection. The board is intended only for simplex operation, does not interface with a PTCC I/O pack, and requires no jumper or hardware-setting changes.

Technical notes
IS210DTTCH1A is the 12-channel DTTC simplex thermocouple terminal board used with VTCC processing.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How many thermocouples terminate on IS210DTTCH1A?
IS210DTTCH1A accepts twelve thermocouple inputs on its fixed 42-position terminal block.
Can one VTCC process more than one IS210DTTCH1A?
Yes. One VTCC can connect to two IS210DTTCH1A boards, providing 24 thermocouple inputs in total.
Where should cable shields land on IS210DTTCH1A?
Every third field-terminal screw on IS210DTTCH1A is assigned to shielding, while terminals 41 and 42 are SCOM connections.
Why would IS210DTTCH1A report an open thermocouple?
IS210DTTCH1A uses open-circuit injection and channel limit checks, allowing VTCC diagnostics to distinguish an open input from a valid measurement.
A cabinet uses PTCC processing; can IS210DTTCH1A be its field board?
IS210DTTCH1A belongs to the simplex VTCC path, so it is not the thermocouple terminal board assigned to PTCC processing.
Must jumpers be set for thermocouple type on IS210DTTCH1A?
No hardware jumpers are provided on IS210DTTCH1A; thermocouple processing is handled through the VTCC configuration.
