IS230TDBTH6A GE MKVIe Discrete Input/Output, 125 V dc, Qty. 1 PDIO I/O pack, DIN-rail mount

Description:

The Simplex Discrete Input/Output (TDBT) terminal board is a simplex contact input/output terminal board designed for DIN-rail or flat mounting. 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. TDBS provides 12 form-C relay outputs and accepts different option cards to expand relay functions.

Mark VIe Systems
In the Mark* VIe systems, the PDIO I/O pack works with the TDBS. The I/O pack plugs into the D-type connector and communicates with the controller over Ethernet. A single connection point for PDIO is provided with one or two network connections possible from PDIO to the controllers.

Board Versions
Three versions of TDBS are available as follows:

There are three option boards available that plug on to TDBS:

• IS200WROB turns the relay portion of TDBS into the functional equivalent of IS200TRLYH1B. This option provides fused and sensed power distribution to the first six relay outputs and dedicated power to the last relay output.
• IS200WROF puts a single fuse in series with each relay common connection. Fuse voltage feedback is included.
• IS200WROG distributes power from an input connector to each relay through a single fuse. Fuse voltage feedback is included.

To install the PDIA pack
Installation
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 point terminal blocks, typically using #18 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. Shields should be terminated on a separate bracket.

Operation
The function and on-board signal conditioning are the same as those on TBCI, they are scaled for 24, 48, and 125 V dc excitation. The input excitation range is 16 to 32 V dc, 32 to 64 V dc, and 100 to 145 V dc respectively. The threshold voltage is 50% of the excitation voltage. The contact sensing circuits are shown in the figure.The processor board in the pack is common to all Mark VIe Ethernet I/O packs. It contains the following:
• High-speed processor with RAM and flash memory
• Two fully independent 10/100 Ethernet ports with connectors
• Hardware watchdog timer and reset circuit
• Internal I/O pack temperature sensor
• Infrared serial communications port
• Status-indication LEDs
• Electronic ID and the ability to read IDs on other boards
• Substantial programmable logic supporting the acquisition board
• Input power connector with soft start/current limiter
• Local power supplies, including sequencing and monitoring
An industry-standard infrared serial communications port is provided on the processor board. Accessible through the pack front, this port provides diagnostic information on the pack status and an ability to program the pack when both Ethernet connections fail. It is possible to communicate with this port using most notebook computers and most hand-held Personal Digital Assistants (PDA).
