FUNCTIONAL DESCRIPTION:

IS200DTAIH1AAA is a Simplex Analog Input/Output Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Control Systems. The Simplex Analog Input/Output (DTAIH1AAA) terminal board is a compact analog input terminal board designed for DIN-rail mounting. The board has 10 analog inputs and 2 analog outputs and connects to the VAIC processor board with a single cable. This cable is identical to those used on the larger TBAI terminal board. The terminal boards can be stacked vertically on the DIN-rail to conserve cabinet space. 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 a 0-200 mA current. Two DTAIH1AAA boards can be connected to VAIC for a total of 20 analog inputs and 4 analog outputs. Only a simplex version of the board is available. The functions and on-board noise suppression are the same as those on the TBAI. High-density euro-block type terminal blocks are permanently mounted to the board, with two screw connections for the ground connection (SCOM). An on-board ID chip identifies the board to the VAIC for system diagnostic purposes.

INSTALLATION:

Mount the plastic holder on the DIN-rail and slide the DTAIH1AAA board into place. Connect the RTD wires directly to the terminal block. The Euro-block type terminal block has 48 terminals and is permanently mounted on the board. Typically, #18 AWG wires (shielded twisted pair) are used. Two screws, 43 and 44, are provided for the SCOM (ground) connection, which should be as short a distance as possible. DTAIH1AAA accommodates the following analog I/O types:

• Analog input, two-wire transmitter
• Analog input, three-wire transmitter
• Analog input, four-wire transmitter
• Analog input, externally powered transmitter
• Analog input, voltage ±5 V, ±10 V dc
• Analog output, 0-20 mA current
• Analog output, 0-200 mA current

OPERATION:

The DTAI module provides a built-in 24 V DC power supply for all connected transducers, simplifying field wiring and eliminating the need for external excitation sources. Each analog input channel can be independently configured for either current or voltage mode through onboard jumper settings, offering flexibility for various sensor types and signal ranges.

For output capabilities, the module includes two analog output circuits. One output is fixed as a 4–20 mA current loop, while the second output is fully jumper-configurable to operate either in 4–20 mA mode or as a high-current 0–200 mA source, depending on application requirements.

Unlike the TBAI module, the DTAI features a single cable interface. Due to this single-connection architecture, it is not suitable for Triple Modular Redundancy (TMR) configurations, where three fully independent signal paths are required to maintain fault tolerance and voting integrity.
