FUNCTIONAL DESCRIPTION:

IS230STAI2ASTAI2AG11 is a Dual Basic Analog I/O Assembly Module manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed 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 BPx 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. 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:

1. The PAIC I/O pack includes one of several compatible BPx processor boards used for handling analog input and output functions in control systems. Depending on the model, it contains either:
2. A BPPB processor board (used in models PAICH1A and PAICH2A), or
3. A BPPC processor board (used in models PAICH1B and PAICH2B), which is functionally compatible and supported from ControlST software version V04.03 onwards.
4. Models PAICH2A and PAICH2B offer additional hardware that enables them to support 0–200 mA current output on the first output channel, which extends their capability beyond standard configurations.

SUPPORTED REDUNDANCY CONFIGURATIONS:

Simplex Configuration: This setup uses a single PAIC I/O pack, which can be connected to the network through one or two Ethernet connections. It is the most common and basic configuration, suitable for standard system needs.

Triple Modular Redundancy (TMR): This is a high-reliability configuration where three PAIC I/O packs are used. Each I/O pack is independently connected to the network, ensuring redundancy and increased system resilience. This setup is only supported when using the TBAIH1C terminal board.

Dual Configuration: The PAIC does not support dual configurations with any of the mentioned terminal boards. In other words, using two I/O packs with shared control in a dual setup is not permitted or supported.

INSTALLATION:

• 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.
• The I/O pack mounts directly to the terminal board. The simplex terminal board has a single DC-37 pin connector that receives the I/O pack. The TMR-capable terminal board has three DC-37 pin connectors and can also be used in simplex mode if only one I/O pack is installed. The I/O pack directly supports all of these connections.
• 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 ENET1 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. It is not necessary to remove power from the cable before plugging it in because the I/O pack has inherent soft-start capability that controls current inrush on power application.

FREQUENTLY ASKED QUESTIONS:

How many analog input channels does the PAIC support?

The PAIC module supports up to 10 analog input channels. Channels 1 through 8 can be configured to accept a wide range of signals, including ±5 V, ±10 V, and 4–20 mA current loops. Channels 9 and 10 are designed specifically for ±1 mA or 4–20 mA current inputs, providing flexibility for various sensor types and applications.

What types of analog output signals are supported?

PAIC modules support current-loop-based analog outputs. The PAICH1 variant provides two outputs rated for 0–20 mA, which is standard for most control applications. The PAIC2 variant includes enhanced output capability, where the first channel supports up to 0–200 mA, allowing for high-current analog control where required.

Which terminal boards are compatible with the PAIC module?

PAIC modules are compatible with several terminal boards, including TBAIH1C, STAIH1A, STAIH2A, SAIIH1A, and SAIIH2A. The TBAIH1C board supports both Simplex and TMR systems, while the STAIH and SAIIH models are for Simplex use only. It is important to note that DIN rail-mounted DTAI terminal boards are not supported with the PAIC module.
