GE IS200TBAOH1C Analog Output Terminal Board
Description:
IS200TBAOH1C is designed as GE Analog Output (TBAO) terminal board. IS200TBAOH1C supports 16 analog outputs with a current range of 0-20 mA. Current outputs are generated by the PAOC l/O pack, The outputs have noise suppression circuitry to protect against surge and high-frequencynoise. The TBA( has two barrier-type terminal blocks for customer wiring and six D-type cable connectors.
Driven devices should not exceed a resistance of 900 2 and can be located up to 300 m (984 ft) from the control cabinet, The PAOC contains the D/A converter and drivers that generate the controlled currents. T'he output cuent is measured by the voltage drop across a resistor on the terminal board. Filters reducehigh-frequency noise and suppress surge on each output near the point of signal exit. The following figure displays IS200TBAOH1C in a simplex system.

Q&A:
1. How to install IS200TBAOH1C?
Attach the IS200TBAOH1C to a vertical mounting plate. Connect the wires for the 16 analog outputs directly to the two l/O terminal blocks mounted on the let of the board. Each point can accept two 3.0 mm (#12AWG) wires with 300 V insulation per poinusing spade or ring type lugs. Each block is held down with two screws and has 24 terminals. A shield terminal strip attached to chassis ground is located immediately to the left of cach terminal block. IS200TBAOH1C works with PAOC I/O pack(s) and supports simplex applications only. The l/O pack(s) plug into the D-type connectors and communicate over lONet Ethernet with the Mark Vle controller. Special side mounting brackets support the lO pack(s).

2. How to make a diagniostic test on the IS200TBAOH1C?
Diagnostic tests are made on the terminal board as follows:
• The board provides the voltage drop across a series resistor to indicate the output current. The l/O pack creates a diagnostic alarm (fault) if any one of the eight outputs goes unhealthy.
• Each cable connector on the terminal board has its own lD device that is interrogated by the l/O pack. The lD device is a read-only chip coded with the terminal board serial number, board type, revision number, and the JR, JS, JT connector location. When this chip is read by the l/0 pack and a mismatch is encountered, a hardware incompatibility fault is created.
