FUNCTIONAL DESCRIPTION:

IS220PAICH2B, REV B is a Thermocouple Analog I/O Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. The Analog I/O pack (PAIC) provides the electrical interface between one or two I/O Ethernet networks and an analog input terminal board. The PAIC contains a BPPX processor board and an acquisition board specific to the analog input function. The I/O pack is capable of handling up to 10 analog inputs, the first eight of which can be configured as ±5 V or ±10 V inputs, or 4-20 mA current loop inputs. The last two inputs may be configured as ±1 mA or 4-20 mA current inputs.

The load terminal resistors for current loop inputs are located on the terminal board and voltage is sensed across these resistors by the PAIC. The PAICHI also includes support for two 0-20 mA current loop outputs. The PAICH2 includes extra hardware to support 0-200 mA current on the first output. Input to the I/O pack is through dual RJ-45 Ethernet connectors and a three-pin power input. Output is through a DC-37 pin connector that connects directly with the associated terminal board connector. Visual diagnostics are provided through indicator LEDs.

COMPATIBILITY:

• The PAIC I/O pack includes one of the following compatible BPPx processor boards. The PAICHIA and H2A contain a BPPB processor board.
• The PAICHIB and H2B contain a functionally compatible BPPC that is supported in the ControlST software suite V04.03 and later.
• PAICH2A and H2B also include extra hardware to support 0-200 mA current on the first output.
• The PAIC is compatible with the analog input terminal board (TBAIHIC), and the STAI board, but not the DIN rail-mounted DTAI board. The PAIC is only compatible with the HIC version of TBAI and will report compatibility problems with any of the earlier revisions. No physical damage will result if a PAIC is powered up on an older board in error.

CONNECTORS:

A DC-37 pin connector on the underside of the I/O pack connects directly to the discrete input terminal board. The connector contains the 24 input signals, ID signal, relay coil power, and feedback multiplex command.

• An RJ-45 Ethernet connector named ENETI on the side of the pack is the primary system interface.
• A second RJ-45 Ethernet connector named ENET2 on the side of the pack is the redundant or secondary system interface.
• A 3-pin power connector on the side of the I/O pack is for 28 V dc power for the I/O pack and terminal board.

FREQUENTLY ASKED QUESTIONS:

What is a Thermocouple Analog I/O Terminal Board?

A Thermocouple Analog I/O Terminal Board is a specialized interface device used to connect thermocouples to control systems, programmable logic controllers (PLCs), or monitoring equipment. It facilitates the conversion of thermocouple signals into analog signals that can be accurately read and processed by the connected system for precise temperature measurement and control.

What types of thermocouples are supported?

Most Thermocouple Analog I/O Terminal Boards are compatible with multiple thermocouple types, such as J, K, T, E, N, R, and S. The specific thermocouple types supported depend on the design and configuration of the board, as outlined in the manufacturer’s specifications.

What are the key features of a Thermocouple Analog I/O Terminal Board?

These boards typically include multi-channel input capabilities, high accuracy, and built-in linearization for precise temperature measurements. They also feature cold junction compensation (CJC) to address environmental temperature variations, signal isolation to protect against electrical noise, and overvoltage protection for added reliability in industrial environments.
