Functional Description
IS230STAI2AH01 is a Simplex Analog Input terminal board developed by GE. It is a part of Mark VIe control system.It is designed to handle analog signal interfacing between field devices and the control system.
Analog Inputs
- The board is equipped with 10 analog input channels.
- It supports multiple wiring configurations. Two-wire, three-wire, four-wire, and externally powered transmitters.
- These channels are used to receive standard analog signals such as 4–20 mA or 0–5 V/0–10 V, depending on system setup and external transmitter type.
- The inputs are typically used for process measurements like temperature, pressure, level, and flow.
Analog Outputs
- There are two analog output channels on the board.
- By default, both outputs operate in the 0–20 mA range.
- Channel 1 can be jumper-configured to output 0–200 mA, allowing integration with devices requiring higher current signals.
- Analog outputs are commonly used for retransmission to control valves, indicators, or other systems.
Architecture and Configuration
- The board is intended for simplex configurations only, meaning it does not support redundancy.
- It is typically used in applications where non-redundant analog I/O is sufficient or where cost and space constraints are a consideration.
- The board interfaces directly with an I/O pack in the Mark VIe system, which handles digitization and communication.
Terminal Design
- High-density Euro-block terminal connectors are used to reduce footprint and support field wiring.
- These connectors allow quick and secure wire termination and are suitable for industrial environments.
Board Identification and Diagnostics
- An onboard ID chip provides identification information to the I/O pack.
- This is used for system diagnostics, inventory, and configuration validation during operation and maintenance.
Installation
- The terminal board is installed with a plastic insulator that provides isolation and support. This assembly is typically mounted on a sheet metal carrier, which is then attached to a DIN rail within the control cabinet. For installations where DIN rails are not used, the board and insulator can also be mounted on a sheet metal plate and bolted directly to the cabinet structure. This flexibility allows the board to be integrated into different cabinet designs based on system requirements.
- Two types of Euro-block terminal configurations are available for the board. The STAI_1 version comes with a permanently mounted 48-terminal Euro-block. This fixed configuration ensures a secure and stable connection. In contrast, the STAI_2 version features a right-angle header that accepts a range of commercially available pluggable Euro-blocks, also with 48 terminals. This allows for easier field service and replacement without disturbing the wiring.
- Wiring to the board is typically done using #18 AWG shielded twisted pair cables, which help reduce electrical noise and improve signal integrity. A dedicated shield termination point is provided near the terminal blocks for proper grounding of cable shields, which is essential for maintaining accurate analog signal transmission.
- The board is capable of handling various analog input types, including two-wire, three-wire, and four-wire transmitter configurations, as well as externally powered transmitters. It also supports voltage input ranges of ±5 V and ±10 V DC. For outputs, the board provides two current output channels in the 0–20 mA range, with one channel configurable to output 0–200 mA through onboard jumpers. This allows compatibility with different field devices and signal requirements.
