Functional Highlights & System Integration

• The IS200TDBTH6A operates as a TMR contact input/output terminal board for Mark VIe control systems.
• External sources supply nominal 24, 48, or 125 V dc wetting voltage to the 24 group-isolated contact inputs.
• Hardware filters guard against surges and high-frequency noise, ensuring stable signal acquisition.
• Three PDIO I/O packs connect via D-type connectors and communicate with controllers through Ethernet.
• Each PDIO links to a specific TMR controller – JR1 to R controller, JS1 to S controller, and JT1 to R/S controllers.
• Resettable polymer PTC fuses limit the 24 V dc supply to 0.5 A, protecting downstream circuits.

Installation & Mounting Guide

• Mount the IS200TDBTH6A on a DIN rail using the included sheet metal carrier and plastic insulator.
• Alternatively, attach the board assembly inside a cabinet with standard fasteners for permanent installation.
• Use #18 AWG wires to connect to two sets of 48 terminal blocks for reliable field wiring.
• Connect input contact circuits to the lower terminal set (TB2) and relay outputs to the upper set (TB1).
• Use a separate bracket to terminate shields and maintain signal integrity.

Relay Outputs & Optional Board

• When using a relay option board, plug it into JW1 and JW2 connectors on the IS200TDBTH6A for expanded functionality.
• Each relay terminal point on TB1 corresponds to specific relay outputs, detailed in the board's manual.
• If external power is necessary, wire it directly to the connector on the option board.
• Six jumpers on the optional WROBH1 board allow you to enable or disable individual relays.
• Remove a jumper when using dry contacts and no power distribution is required.

Operating Specifications & Signal Conditioning

• The onboard signal conditioning matches the STCI board and supports 24, 48, and 125 V dc wetting voltages.
• Input wetting voltage ranges: 16–32 V dc, 32–64 V dc, and 100–145 V dc respectively.
• Threshold voltage equals half of the wetting voltage for precise switching.
• Contact input currents are resistance-limited to 2.5 mA (first 21 circuits) and 10 mA (circuits 22–24).
• Polymer PTC fuses provide overcurrent protection for the 24 V dc supply, rated at 0.5 A.

Configuration & Physical Characteristics

• The IS200TDBTH6A has no onboard jumpers or hardware configurations – a plug-and-play design.
• Conformal coating protects the PCB against moisture, dust, and chemical contaminants.
• Surface mount technology allows compact component placement and high reliability.
• Visual features include 12 large potentiometers, MOVs for surge protection, and integrated circuits for signal processing.
• This assembly carries a functional revision A and grouping Group 6 under the Mark VI series.

Frequently Asked Questions (FAQ)

• Is the IS200TDBTH6A a brand new original product?
