SIGNAL ROUTE
Field contact → TDBT terminal → signal conditioning → PDIO I/O pack → Ethernet → controller
|

|
CONTACT INPUT PERFORMANCE
The H2 configuration uses a nominal 24 VDC floating wetting supply with an operating range of 16 to 32 VDC.
The first 21 circuits draw approximately 2.5 mA, while circuits 22 through 24 draw approximately 10 mA.
The 24 VDC supply path is current-limited to 0.5 A through resettable polymer positive-temperature-coefficient protection.
Input circuitry uses a 4 ms hardware filter and a sensing threshold equal to approximately 50% of the applied wetting voltage.
|
RELAY RESPONSE & FEEDBACK
Each TDBT board provides 12 relay channels with normally closed, common, and normally open contact functions.
Typical relay response time is 25 ms for both energizing and de-energizing transitions.
Relay position feedback uses a contact pair separate from the load contacts for status monitoring.
Typical relay contact life is 100,000 electrical operations and 5,000,000 mechanical operations in the applicable configuration.

|
Can IS200TDBTH2ABC replace another TDBT H2 board directly?
Replacement should be checked against the complete board part number, hardware revision and the installed Mark VIe I/O arrangement. The H2 configuration is specifically associated with nominal 24 VDC contact wetting, so a board intended for a different wetting-voltage group should not be treated as an automatic equivalent.
|
|
How should IS200TDBTH2ABC be matched with the PDIO arrangement?
TDBT provides three PDIO connection points. In a redundant controller arrangement, the PDIO connections are associated with the corresponding controller paths; in TMR operation, each PDIO connection can lead to its respective controller. The installed architecture should therefore be checked before replacing or rewiring the terminal board.
|
|
What should buyers verify before ordering IS200TDBTH2ABC for a 24 VDC field circuit?
Verify that the field contact circuits use the H2 24 VDC wetting arrangement. The specified operating range is 16–32 VDC, with a sensing threshold of approximately 50% of the applied wetting voltage. The input-current characteristics and wiring arrangement should also match the existing installation.
|
|
Can IS200TDBTH2ABC handle relay loads without an additional option board?
The TDBT base board already provides 12 Form-C relay channels. Depending on the intended output-power arrangement, an optional WROB board can be used to expand relay-related functions. The external load voltage and current must remain within the applicable relay ratings.
|
|
What should be checked when replacing IS200TDBTH2ABC during a Mark VIe maintenance shutdown?
Match the complete part number and hardware revision, confirm the H2 24 VDC input arrangement, record the TB1 and TB2 field wiring positions, and verify the JR1, JS1 and JT1 PDIO connections before removing the existing board. The relay and contact-input wiring should be restored to the corresponding terminal positions during replacement.
