FUNCTIONAL DESCRIPTION:

IS200STAIH2ABA is a Simplex Analog Input Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in distributed control systems. The STAI board is a compact analog input terminal board that accepts 10 analog inputs and two analog outputs and connects to the PAIC pack. The 10 analog inputs accommodate two-wire, three-wire, four-wire, or externally powered transmitters. The two analog outputs are 0-20 mA, but one can be jumper configured to 0-200 mA current. Only a simplex version of the board is available. High-density Euro-block type terminal blocks are used. An on-board ID chip identifies the board to the PAIC for system diagnostic purposes. The PAIC I/O pack works with the STAI. The I/O pack plugs into the D-type connector and communicates with the controller over Ethernet. Only simplex systems are supported.

STAI INSTALLATION:

A sheet metal carrier that is mounted on a DIN-rail carries the STAI together with a plastic insulator. The STAI plus insulator can alternatively be mounted to a sheet metal assembly before being fastened directly to a cabinet. Typically, shielded twisted pair (#18 AWG) wires are utilized. There is an I/O cable shield terminal available next to the terminal blocks. It is possible to accept the following analog input and output types:

• Two-wire transmitter with analog input.
• Three-wire transmitter with analog input.
• Four-wire transmitter with analog input.
• An externally powered transmitter with an analog input.
• Analog input, 5 and 10 volts direct current.
• 0-20 mA current analog output.
• Analog output, current of 0-200 mA.

STAI OPERATION:

The terminal board provides a 24 V DC power supply for all transmitters and transducers. Users can select between current or voltage inputs by adjusting the jumper settings. The system offers two analog output circuits: one is fixed at 4-20 mA, while the other can be configured via jumpers to either 4-20 mA or 0-200 mA, depending on the user's preference. Notably, there is only a single cable connection available, which means the terminal board is unsuitable for TMR (Triple Modular Redundancy) applications, unlike the TBAI model.

STAI DIAGNOSTICS:

The output current is shown by the voltage drop across a series resistor on the board. A diagnostic alarm (fault) is generated by the I/O processor if either of the two outputs becomes unhealthy. The I/O controller queries each ID device that each cable connector on the terminal board has to offer.

The terminal board serial number, board type, revision number, and the placement of the JR, JS, and JT connectors are all encoded on a read-only chip known as the ID device. A hardware incompatibility fault is produced when the I/O controller reads this chip and runs across a mismatch.

STAI CONFIGURATION:

Jumpers are used to configure the terminal board. Refer to the installation diagram to determine where these jumpers should be placed. The available jumpers are as follows:

• Current input or voltage input can be chosen using the jumpers J1A through J8A.
• Whether the return is linked to common or left open is determined by jumpers J1B through J8B.
• The input current is chosen between 1 mA and 20 mA using the jumpers J9A and J10A.
• Whether the return is linked to common or left open is determined by jumpers J9B and J10B.
• Output 1 is adjusted to 20 mA or 200 mA by jumper J0.

FREQUENTLY ASKED QUESTIONS:

What is the input voltage range for the Simplex Analog Input Terminal Board?

The input voltage range for the Simplex Analog Input Terminal Board is typically designed to work with 24 V DC power supplied to the transmitters and transducers.

How do I configure the analog output for a 0-200 mA range?

To configure the analog output for a 0-200 mA range, adjust the jumper settings on the terminal board to switch the output circuit from the default 4-20 mA to the 0-200 mA configuration.

What is the maximum current that can be drawn from the analog outputs?

The terminal board supports output ranges of 4-20 mA and 0-200 mA. The maximum current for the 0-200 mA output configuration would be 200 mA.
