GE IS400TDBTH6A Discrete Input/Output Terminal Board

GE IS400TDBTH6A Discrete Input/Output Terminal Board

The IS400TDBTH6A Discrete Input/Output (TDBT) terminal board is used for TMR redundancy with either DIN-rail or flat mounting. Three PDIO I/O packs plug into D-type connectors and communicate with the controllers over Ethernet. The TDBT board accepts 24 group-isolated contact inputs that are supplied with a nominal 24, 48, or 125 V dc wetting voltage from an external source. The contact inputs have noise suppression to protect against surge and high-frequency noise. TDBT provides 12 form-C relay outputs and accepts the WROB option board to expand relay functions. All terminal board versions have pluggable terminal blocks.

Three connection points for the PDIO I/O pack are provided. With dual controllers the PDIO on TDBT connector JR1 would be networked to the R controller, JS1 PDIO to the S controller, and JT1 PDIO to both R and S controllers. With TMR controllers one network connection is provided to each PDIO leading to the respective controller. TDBT is not designed to operate correctly with a single PDIO I/O pack.

The WROBH1A is an option board that plugs into TDBTH2A, H4A, or H6A to provide fused and sensed power distribution to the first six relay outputs and dedicated power to the last relay output. The WROFH1A and WROGH1A option boards are not compatible with the TDBT terminal board.

TDBT Layout

The TDBT plus a plastic insulator mounts on a sheet metal carrier that then mounts on a DIN rail. Optionally the TDBT plus insulator mounts on a sheet metal assembly that then bolts in a cabinet. The connections are wired directly to two sets of 48 terminal blocks, typically using #24 - #12 AWG wires. The upper set of terminals, TB1, connects to the relay portion of the board and the lower set of terminals, TB2, connect to the contact input circuits. Screw assignments for the two sets of terminals are identical to those found on the SRLY relay board and the STCI contact input terminal board. Shields should be terminated on a separate bracket.

For IS400TDBTH6A, the wetting voltage output terminals are all in parallel and fed from the positive voltage applied to JE1 pin 1. It is permissible to run a single wetting voltage lead from the board terminal to a group of remote contacts and then bring the individual contact wires back to the inputs. Negative or return wetting voltage is supplied by JE1 pin 3.
