Installation Guide – IS200TBAIH1C

• Connect input and output wires directly to two I/O terminal blocks on the board.
• Each block has 24 terminals and accepts up to #12 AWG wire.
• Each block is held down with two screws for secure mounting.
• A shield terminal attachment point sits next to each terminal block.
• Use jumper J0 to select 20 mA or 200 mA output current.
• Use jumpers J1A–J8A to select current or voltage input.
• Use jumpers J1B–J8B to connect return to common or leave open.
• Use jumpers J9A/J10A and J9B/J10B for 1 mA or 20 mA input current and return setting.
• For TMR systems, plug three PAICs directly into the IS200TBAIH1C (Mark VIe) or cable to three VAIC boards (Mark VI).
• For simplex, use connector JR1 only.

Commissioning and Maintenance Convenience

• Diagnostics monitor each output and report faults to the I/O processor.
• A suicide relay in the I/O controller disconnects the faulty output if the processor command cannot clear the fault.
• The connector ID chip stores serial number, board type, revision, and connector location – the controller reads it automatically.
• Any mismatch triggers a hardware incompatibility fault, simplifying troubleshooting.
• 24 V dc source powers transducers with short-circuit protection, reducing downtime.
• In TMR mode, the board diode-shares 24 V power from all three controllers for redundancy.
• Analog output current is measured with a series resistor and fed back to each controller for median voting.

Compatibility Notes

• Mark VI Systems: Works with VAIC processor. One or two TBAIs can connect to one VAIC. TMR requires three VAIC boards.

• Supports simplex and TMR architectures.
• Accepts two-wire, three-wire, four-wire, and externally powered transmitters.
• Voltage inputs: ±5 V dc and ±10 V dc.
• Outputs configurable for 0–20 mA or 0–200 mA current.
• Designed for direct wiring to two I/O terminal blocks with up to #12 AWG wire.

Expert Review

Industrial automation engineers value the IS200TBAIH1C for its robust signal handling and dual-system compatibility. The board’s noise suppression circuitry and short-circuit protected 24 V outputs reduce field failures. The TMR median voting feature adds a layer of reliability for critical loops. The ID chip simplifies spare-part verification. One minor limitation is the lack of published frequency response data, so users should confirm dynamic requirements with the factory. Overall, this terminal board delivers solid performance for Mark VI and Mark VIe installations that demand accurate analog I/O with minimal maintenance.

Manager’s Insight

From a sourcing perspective, the IS200TBAIH1C is a smart investment because it covers both Mark VI and Mark VIe platforms. This reduces spare-parts inventory. The 12-month warranty and 12–24 hour dispatch from Powergear X keep downtime low. We see strong demand from power plants and process industries that run TMR systems. The board’s ability to fan out inputs to three controllers and vote output currents makes it a cost-effective redundancy solution. For buyers who need fast delivery, we ship via FedEx, UPS, and DHL.

Frequently Asked Questions (FAQ)

Q: Can I use the IS200TBAIH1C in a simplex Mark VIe system?
A: Yes. Connect a single PAIC to the board. Use connector JR1 for simplex operation.

Q: What is the maximum cable length for analog inputs?
A: The board supports up to 300 m (984 ft) of cable with 15 Ω maximum two-way lead resistance.

Q: How do I set the output current to 0–200 mA?
A: Use jumper J0. Place it in the 200 mA position. The default is 0–20 mA.

Q: What happens if a connector ID chip does not match?
A: The I/O controller reads the chip and creates a hardware incompatibility fault. Check that the board type and revision match your system.

Q: Can the board power transmitters directly?
A: Yes. Each 24 V dc output delivers 21 mA and is short-circuit protected. You can also use externally powered transmitters.

Q: How does TMR output voting work?
A: Each controller feeds current to the output. A series resistor measures total current and sends voltage back to each controller. The final output is the median of the three currents.

Q: What is the warranty period?
A: Powergear X provides a 12-month warranty on the IS200TBAIH1C.

Q: How fast do you ship?
A: We dispatch within 12–24 hours after order confirmation. We use FedEx, UPS, and DHL for worldwide delivery.

Q: Do you provide bulk pricing for system integrators?
A: Yes. Email sales@powergearx.com or message +86 18030005825 on WhatsApp with your quantities for a quote.

Q: Can I replace a TBAIH1B with this model?
A: Check the output load ratings. The TBAIH1C supports 800 Ω for 4–20 mA with VAICH1D or PAIC. Confirm your VAIC version with our team before ordering.

Buying Guide

• Confirm your control system: Mark VI (VAIC) or Mark VIe (PAIC).
• Decide between simplex (one connector) and TMR (three connectors) operation.
• List your input types: two-wire, three-wire, four-wire, externally powered, or voltage.
• Check your required output current: 0–20 mA or 0–200 mA.
• Verify cable length and lead resistance stay within 300 m and 15 Ω.
• For TMR, ensure you have three PAICs (Mark VIe) or three VAIC boards (Mark VI).
• Review the output load requirement: 500 Ω or 800 Ω depending on processor model.
• Order spare units to reduce downtime – the board’s diagnostics help pinpoint faults quickly.
