Product Introduction
IS200TBAIH1C Analog Input/Output (TBAI) terminal board supports 10 analog inputs and 2 outputs. The 10 analog inputs accommodate two-wire, three-wire, four-wire, or externally powered transmitters. The analog outputs can be set up for 0-20 mA. Inputs and outputs have noise suppression circuitry to protect against surge and high frequency noise. The TBAI has three DC-37 pin connectors for TMR I/O packs. Simplex I/O redundancy is also supported using a single JR1 connection.

Product Details
With TMR I/O redundancy, the input signals are fanned to the three connectors for the R, S, and T I/O packs. TMR outputs combine the current of the three connected output drivers and determine the total current with a measuring shunt. TBAI then presents the total current signal to the I/O packs for regulation to the commanded setpoint.
IS200TBAIH1CDC & IS200TBAIH1CCC Installation:
Connect the input and output wires directly to two I/O terminal blocks mounted on the terminal board. Each block is held down with two screws and has 24 terminals accepting up to #12 AWG wires. A shield terminal attachment point is located adjacent to each terminal block.
• 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 input, current 4-20 mA
• Analog output, 0-20 mA
The following figure displays the wiring connections, jumper positions, and cable connections for TBAI.
TBAI provides a 24 V dc power source for all the transducers. The inputs can be configured as current or voltage inputs using jumpers (JP#A and JP#B). One of the two analog output circuits is 4-20 mA and the other can be configured as 4-20 mA.
Each 24 V dc power output is rated to deliver 21 mA continuously and is protected against operation into a short circuit.Transmitters/transducers can be powered by the 24 V dc source in the control system, or can be independently powered. Jumper JPO selects the type of current output. Diagnostics monitor each output, and a suicide relay in the I/O pack disconnects the corresponding output if a fault cannot be cleared by a command from the processor
In a TMR system, analog inputs fan out to the three I/O packs. The 24 V dc power to the transducers also comes from all three I/O packs and is diode shared on TBAI. Each analog current output is fed by currents from all three I/O packs. The actual output current is measured with a series resistor, which feeds a voltage back to each I/O pack. The resulting output is the voted middle value (median) of the three currents. The following figure displays TBAI in a TMR system.
