CC-PAIH02 51405038-375 Experion PKS High-Level Analog Input Module | Honeywell

Configured for high-level signal acquisition in Experion PKS Series-C control systems, the Honeywell CC-PAIH02 51405038-375 (CC-PAIH02 Analog Input Module) provides direct physical/electrical execution. It handles 16 analog input channels across Input/Output Termination Assembly (IOTA) bus structures.

Hardware Specifications

Channel-to-Channel Isolation and 4-20 mA HART Loop Protocol Execution

The Honeywell CC-PAIH02 51405038-375 analog input module digitized process variables using a high-precision 16-bit A/D converter across a fast 50 ms scan cycle. Each channel interfaces directly with 2-wire or self-powered field transmitters utilizing the 4-20 mA HART loop protocol, as well as 0-5 V, 1-5 V, and 0.4-2 V voltage signals. The internal circuit architecture maintains robust signal conditioning and noise suppression, delivering 70 dB CMRR to safeguard backplane communications against field-side electrical interference and ground loop offsets.

Frequently Asked Questions

Q: How does the CC-PAIH02 module convert 4-20 mA current signals into internal voltage measurements?

A: Current loops are converted into voltage signals internally across precision 250 ohm dropping resistors integrated within the module circuit path.

Q: Can single-ended and differential field inputs be mixed on the same CC-PAIH02 module?

A: Yes, the module natively accommodates up to 12 single-ended channels and 4 differential channels according to the terminal assignments on the corresponding IOTA assembly.

Field Installation Guidelines

1. Mount the Series-C IOTA base securely to the cabinet frame or DIN rail prior to inserting the CC-PAIH02 module.
2. Align the module edge connector pins carefully with the IOTA connector slot and push firmly until the locking tabs snap into place.
3. Terminate 4-20 mA signal wires onto the designated IOTA screw terminals, verifying correct polarity for 2-wire loop-powered or self-powered field transmitters.
4. Separate low-voltage analog signal cables from high-voltage AC power wiring by at least 200 mm to minimize electromagnetic interference.
5. Connect cable shield drains to the cabinet single-point grounding bar to establish effective ground loop isolation.
