IS200TDBTH6A Discrete input/output terminal board

Part Number IS200TDBTH6A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VIe Function Module Availability In StockIS200TDBTH6A is a Discrete Input/Output Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in Distributed Control Systems. The Discrete Input/Output (TDBT) terminal board is a flat or DIN-rail mounted TMR contact input/output terminal board. A nominal 24, 48, or 125 V dc wetting voltage can be provided to the TDBT board's 24 group isolated contact inputs from an external source. The noise suppression on the contact inputs guards against surges and high-frequency noise. In order to increase relay functionality, TDBT offers 12 form-C relay outputs and accepts an option card. The PDIO I/O pack and the TDBT are compatible with MarkVIe systems. Three I/O packs connect to D-type connectors and communicate via Ethernet with the controllers. There are three PDIO connection points available. The PDIO on TDBT connection JR1 would be networked to the R controller, JS1 to the S controller, and JT1 to both the R and S controllers if there were two controllers. Each PDIO connected to a TMR controller receives a single network connection to the corresponding controller. A single PDIO I/O pack cannot be used to properly operate TDBT. INSTALLATION: A sheet metal carrier with the TDBT and a plastic insulator mounted on it installed on a DIN rail. Alternately, the TDBT + insulator attaches to a sheet metal assembly that is subsequently fastened within a cabinet. In general, 18 AWG wires are used to directly wire the connections to two sets of 48 terminal blocks. Input contact circuits are connected to the lower set of terminals, TB2, while the relay section of the board is connected to the upper set of terminals, TB1. Both the SRLY relay board and the STCI contact input terminal board's screw assignments apply to the two sets of terminals. A separate bracket should be used to end shields. RELAY OUTPUTS: When a relay option board is utilized, it is plugged into the TDBT connections JW1 and JW2 and secured there by the connectors' grip. Please contact us.

The role of each relay terminal point designated as TB1 in relation to the existence of an option board is detailed in the following table. If additional power needs to be delivered from an external source, it is wired to a connector on the option board. OPERATION: The onboard signal conditioning and contact input function are identical to those on STCI and are scaled for 24, 48, and 125 V dc wetting voltage. 16 to 32 V dc, 32 to 64 V dc, and 100 to 145 V dc, respectively, make up the input wetting voltage range. The wetting voltage is half of the threshold voltage. The description of the I/O pack includes a diagram of the touch-sensing circuitry. On the first 21 circuits and on circuits 22 through 24, contact input currents are resistance limited to 2.5 mA and 10 mA, respectively. Using resettable polymer positive temperature coefficient fuses, the 24 V dc supply of TDBTH2 is currently limited to 0.5 A. CONFIGURATION: The TDBT has no hardware configurations or jumpers. Six jumpers are present on the option board WROBH1 and are used to turn on or off a relay. All six jumpers are assembled while producing boards. When a relay will have dry contacts and power distribution is not needed, the jumper is taken off of the circuit board.T DISCRETE BD TMR TB
