Functional Description

IS230TDBTH6A is an discrete I/O board developed by GE. It is a part of Mark VIe control system. The Discrete Input/Output terminal board is used for TMR redundancy with either DIN-rail or flat mounting. Three PDIO I/O packs connect to the controllers via Ethernet and plug into D-type connectors. The board is a TMR contact input/output terminal board that can be mounted on a DIN-rail or flat surface. The board accepts 24 group isolated contact inputs from an external source with a nominal 24, 48, or 125 V dc wetting voltage. To protect against surge and high-frequency noise, the contact inputs have noise suppression. The TDBT has 12 form-C relay outputs and can be expanded with an option card. The PDIO I/O pack works with the TDBT in Mark VIe systems. Three I/O packs connect to the controllers via D-type connectors and communicate via Ethernet. Three PDIO connection points are provided. JR1 would be networked to the R controller with dual controllers on the TDBT connector, JS1 to the S controller, and JT1 to both the R and S controllers. TMR controllers provide a single network connection to each PDIO that leads to the respective controller. TDBT is not intended to function properly with a single I/O pack.

Features

  • When using a relay option board, it plugs into TDBT connectors JW1 and JW2 and is held in place by the connectors' force. The table below identifies the function of each relay terminal point labeled TB1 in relation to the presence of an option board. If external power is required, it is connected to a connector on the option board.
  • By monitoring an isolated set of contacts on each relay, the TDBT provides diagnostic feedback to PDIO indicating the state of each relay. All three PDIO packs receive position feedback.
  • When WROB is used in conjunction with TDBT, isolated voltage feedback is used to detect fuse status for the board's six fuse pairs. This feedback is provided by TDBT to all three PDIO packs.

Installation

  • The board, along with a plastic insulator, is mounted on a sheet metal carrier, which is then mounted on a DIN rail.
  • The TDBT plus insulator can be mounted on a sheet metal assembly that is then bolted into 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, is connected to the board's relay portion, while the lower set of terminals, TB2, is connected to the contact input circuits. Screw assignments for the two terminal sets are the same as on the SRLY relay board and the STCI contact input terminal board. Shields should be terminated with their own bracket.

Product Attributes

  • Terminal Blocks: Euro Style Box-type Pluggable
  • Number of Channels: 24 dry contact voltage input channels
  • Input Filter: Hardware filter, 4 ms
  • Fault Detection in I/O Board: Loss of contact input wetting voltage, Non-responding contact input in test mode
  • Max Response Time On: 25 ms typical
  • Max Response Time Off: 25 ms typical
  • Contact Material: Silver-Nickel Alloy

Contact Inputs

  • Contact input connections are made to the 48 terminals labeled TB2 on the terminal board's lower portion.
  • The board receives contact wetting voltage via the JE1 3-pin Mate-n-lok connector on the lower portion of the board. The wetting voltage output terminals are all connected in series and powered by 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 reconnect the individual contact wires to the inputs. JE1 pin 3 provides negative or return wetting voltage.

Configuration

  • On TDBT, there are no jumpers or hardware settings.
  • Option board WROBH1 includes six jumpers for applying or removing power from a relay. Boards are manufactured with all six jumpers installed. When a relay is to be used as dry contacts and power distribution is not required, the jumper is removed from the board.
