IS210DTAIH1AA 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 (DTAI) 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 DTAI 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.


Mount the plastic holder on the DIN rail and slide the DTAI 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.


24 V DC power is available on DTAI for all the transducers and the inputs can be configured as current or voltage inputs using jumpers. One of the two analog output circuits is 4-20 mA, and the other can be jumper configured for 4-20 mA or 0-200 mA. DTAI has only one cable connection so it cannot be used for TMR applications as with TBAI.

What is a Simplex Analog Input/Output Terminal Board?

The Simplex Analog Input/Output Terminal Board is a device used in industrial control systems to interface analog signals between field devices and control systems. It typically converts analog signals such as voltage or current into digital signals that can be processed by the control system, and vice versa.

What are the common applications of the Simplex Analog Input/Output Terminal Board?

It is commonly used in various industrial automation applications such as monitoring temperature, pressure, flow, and other analog parameters in manufacturing plants, refineries, power plants, and other industrial settings.

How does the Simplex Analog Input/Output Terminal Board work?

The board typically consists of analog input channels where signals from sensors or transmitters are connected. These signals are then converted into digital form using analog-to-digital converters (ADCs). Similarly, analog output channels on the board receive digital signals from the control system and convert them into analog signals using digital-to-analog converters (DACs).
