Product Introduction
The Simplex Analog Input/Output (IS200DTAIH1A) 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.

Product Details
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.
Installation
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.
Operation
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 4-20mA, 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.
