Functional Description

IS200STAIS1A is a Simplex Analog Input Board developed by GE. It is a part of Mark VIe control system. The Simplex Analog Input (STAI) terminal board is a compact and versatile device designed for handling multiple analog inputs and outputs. This terminal board is capable of accepting 10 analog inputs and providing two analog outputs.


  • Analog Inputs: The terminal board can accommodate up to 10 analog inputs. Versatility: These inputs can support a range of transmitter types including two-wire, three-wire, four-wire, or externally powered transmitters. This flexibility allows it to interface with a wide variety of sensors and measurement devices.
  • Analog Outputs: The terminal board provides two analog outputs, each designed for a 0-20 mA current range. One of the analog outputs can be configured via a jumper to extend its current range to 0-200 mA, providing additional flexibility for different application requirements.
  • Connectivity: The board connects seamlessly to the pack, ensuring smooth integration into existing systems and facilitating efficient data acquisition and control processes.
  • Simplex Version: Currently, only a simplex version of the board is available, indicating a single-channel configuration which simplifies design and installation while meeting the needs of many standard applications.


  • DIN-Rail Mounting: The STAI, along with the plastic insulator, mounts on a sheet metal carrier. This assembly is then attached to a DIN-rail, which is a standardized mounting system used extensively in industrial control equipment to facilitate organized and efficient installations.
  • Cabinet Mounting: Alternatively, the STAI, along with its insulator, can be mounted on a sheet metal assembly. This assembly is then bolted directly to a cabinet, providing a stable and secure installation within an enclosed environment. This method is ideal for setups that require additional protection and organization within control panels or electrical enclosures.
  • Terminal Block: Features a permanently mounted terminal block with 48 terminals, ensuring robust and reliable connections. In some configurations, the terminal blocks are designed to be pluggable, offering convenience and flexibility with a total of 48 terminals. This design allows for easy connection and disconnection, facilitating maintenance and modifications without disrupting the entire system.
    Wire Specifications: The installation typically uses 18 AWG (American Wire Gauge) wires. These wires are shielded and twisted pairs, which help minimize electrical noise and interference, ensuring accurate signal transmission. An I/O cable shield terminal is provided adjacent to the terminal blocks to further enhance signal integrity and reduce noise.


  • Power Supply: The terminal board provides a 24 V DC power supply, which is available for all connected transmitters (transducers). This centralized power supply simplifies the wiring and installation process, ensuring that all connected devices receive consistent and reliable power.
  • Input Configuration: The terminal board offers flexibility in input configurations, allowing users to select between current and voltage inputs using jumpers. This versatility enables the board to interface with a wide range of sensors and transmitters, accommodating different types of analog signals according to the specific requirements of the application.
  • Analog Output Circuits: One of the two analog output circuits on the board is dedicated to providing a 4-20 mA output. This standard output range is commonly used in industrial control systems for transmitting analog signals over long distances with high accuracy and minimal signal degradation.
  • Configurable Analog Output: The second analog output circuit is designed to be configurable via jumpers. It can be set to operate within the standard 4-20 mA range or can be adjusted to a higher 0-200 mA range. This configurability offers additional flexibility, allowing the board to meet the specific current requirements of various output devices and applications.
  • Single Cable Connection: The terminal board features a single cable connection, which simplifies the overall wiring and installation process. However, this design limitation means that the board is not suitable for Triple Modular Redundancy (TMR) applications, unlike the TBAI terminal board which supports such configurations. TMR applications require multiple cable connections for redundancy and enhanced reliability in critical systems.
