Module Specifications

Backplane Integration and Firmware Logic Processing

The C200H-AD003 module executes direct analog-to-digital data processing while maintaining stable backplane bus communication velocity across the C200H CPU host rack. High-speed analog conversion maps input values straight into CPU memory words without imposing network scan latency. Firmware flash compatibility ensures seamless backplane address recognition across all C200H, C200HS, and C200HX/HG/HE CPU platforms.

Scope of Delivery

• 1 x Omron C200H-AD003 Analog Input Unit
• 1 x Terminal Block Protective Cover
• 1 x Instruction Manual Document

Cabinet Wiring and Installation Steps

• Power Off Unit: Ensure backplane power to the C200H rack is completely switched off before inserting or removing the module.
• Grounding Connection: Connect signal cable shields to a single-point system ground to suppress electromagnetic interference.
• Wiring Route: Separate analog input cables from high-voltage AC lines by at least 200 mm inside cable ducts.
• Terminal Securing: Fasten terminal block screws to 0.8 Nm to maintain continuous electrical contact.

Technical Questions and Answers

• Does the C200H-AD003 module support hot-swapping during CPU execution?

  No, removing or inserting the unit while the backplane is energized risks damaging internal CPU bus logic circuits.

• What backplane current load does the module draw from the 5 VDC rail?

  The internal circuit draws a maximum continuous current of 0.35 A directly from the C200H backplane 5 VDC supply.

• What happens if an analog current loop opens during operation?

  An open loop forces the conversion value to zero or full-scale fault status depending on channel configuration switches.

• How does operating above +55 deg C ambient temperature affect measurement accuracy?

  Temperatures exceeding +55 deg C cause thermal drift, increasing conversion error beyond the rated 1/4000 full scale limit.

• Can voltage and current inputs be mixed on the same module?

  Yes, channels can be configured independently for voltage or current signals using internal terminal connections and DIP switches.

• Is external power required to drive internal conversion logic?

  No external power supply is needed for logic conversion; the module draws operating power directly from the rack backplane bus.

• How do I prevent signal noise from distorting analog conversion words?

  Use twisted-pair shielded cables for all analog inputs and connect the shield exclusively to the functional ground terminal.

• What is the total scan time required for multi-channel processing?

  Conversion requires 2.5 ms per enabled channel, yielding a total conversion cycle time determined by active input count.
