FUNCTIONAL DESCRIPTION:

IS220PAICH1B, REV A is an Analog I/O Module manufactured and designed by General Electric as part of the Mark VIe Series used in GE distributed 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 PAICH1 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. Influt 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 PAICH1B 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.

INSTALLATION:

• Securely mount the desired terminal board.
• Directly plug the PAIC I/O pack into the terminal board connectors.
• Mechanically secure the I/O pack(s) using the threaded studs adjacent to the Ethernet ports. The studs slide into a mounting bracket specific to the terminal board type.
• The bracket location should be adjusted such that there is no right-angle force applied to the DC-37 pin connector between the I/O pack and the terminal board. The adjustment should only be required once in the service life of the product.
• Plug in one or two Ethernet cables depending on the system configuration. The I/O pack will operate over either port. If dual connections are used, the standard practice is to connect ENETI to the network associated with the R controller.
• Apply power to the I/O pack by plugging in the connector on the side of the pack. Removing power from the cable before plugging it in is unnecessary because the I/O pack has inherent soft-start capability that controls current inrush on power application.

OPERATION:

• High-speed processor with RAM and flash memory
• Two fully independent 10/100 Ethernet ports with connectors
• Hardware watchdog timer and reset circuit
• Local ambient temperature sensor
• Infrared serial communications port
• Status-indication LEDs
• Electronic ID and the ability to read IDs on other boards
• Substantial programmable logic supporting the acquisition board
• Input power connector with soft start/current limiter
• Local power supplies, including sequencing and monitoring

FREQUENTLY ASKED QUESTIONS:

How do you connect an Analog I/O Module to a system?

Analog I/O modules connect to the system through physical ports like Ethernet or serial communication ports. These modules also interface with input/output terminal boards for signal processing and conversion.

How is the Analog I/O Module powered?

Analog I/O modules are typically powered through a dedicated power input connector. The control system or an external power source provides the power. Some modules also feature soft-start capabilities, allowing them to be powered on without risking damage due to current surges.

What types of terminal boards are compatible with Analog I/O Modules?

Analog I/O modules are designed to interface with specific terminal boards. Using compatible boards to ensure proper signal conversion and communication is important. Compatibility can vary by manufacturer and model.
