FUNCTIONAL DESCRIPTION:

IS220PAICH2B is an Analog Input/Output 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 (PAICH2B) provides the electrical interface between one or two I/O Ethernet networks and an analog input terminal board. The PAICH2B contains a BPPx processor board and an acquisition board specific to the analog input function. The I/O pack can handle 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 $pm$1 mA or 4-20 mA current inputs.

The load terminal resistors for current-loop inputs are located on the terminal board, and the PAICH2B senses the voltage across these resistors. 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. 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 PAICH2B I/O pack utilizes specific BPPx processor boards tailored to its hardware revision, with the PAICH1A and H2A versions containing a BPPB board, while the PAICH1B and H2B versions utilize a functionally compatible BPPC processor board. It is important to note that the BPPC requires the ControlST software suite V04.03 or later for full support. Furthermore, the PAICH2A and H2B revisions are equipped with specialized hardware designed to support 0–200 mA current on the first output channel.

Regarding terminal board compatibility, the PAIC is designed to interface with the TBAIH1C and STAI boards, but it is explicitly incompatible with the DIN rail-mounted DTAI board. Specifically, the pack is strictly compatible with the H1C version of the TBAI; attempting to power it up on any earlier revision will trigger a system compatibility report. However, while such a mismatch will cause software errors, powering a PAIC on an older board in error will not result in any physical damage to the hardware.

INSTALLATION:

The installation of the PAIC I/O pack involves mounting the terminal board and securing the pack through specific electrical and mechanical steps. First, the desired terminal board must be securely mounted. The I/O pack is then plugged directly into the terminal board connectors. To ensure mechanical stability, the pack is secured using threaded studs located adjacent to the Ethernet ports; these studs slide into a mounting bracket that must be adjusted to prevent any right-angle force from being applied to the DC-37 pin connector. This adjustment is typically only necessary once during the product's service life. Connectivity and power application follow these steps:

• Terminal Board Types: The I/O pack mounts directly to either a simplex terminal board, which has one DC-37 pin connector, or a TMR-capable terminal board, which features three connectors and can operate in simplex mode if only one pack is installed.

• Network Connection: Depending on the configuration, one or two Ethernet cables are plugged in. While the pack can operate over either port, standard practice for dual connections is to link ENET1 to the network associated with the R controller.

• Power Application: Power is applied by plugging the connector into the side of the pack. Due to an inherent soft-start capability that manages current inrush, it is not necessary to remove power from the cable before plugging it in.

CONNECTORS:

• DC-37 Pin Connector: Located on the underside of the I/O pack, this connector plugs directly into the associated terminal board (such as the TBAIH1C or STAI). It carries 24 input signals, ID signals, relay coil power, and feedback multiplex commands.

• Ethernet Connectors (Dual RJ-45): The side of the pack contains two ports labeled ENET1 and ENET2. ENET1 serves as the primary system interface, typically connected to the network associated with the R controller, while ENET2 serves as the redundant or secondary interface.

• 3-Pin Power Connector: Situated on the side of the pack, this connector provides 28 V dc power to both the I/O pack and the connected terminal board.
