Features:
- Sixteen high-level transmitter inputs, 16-bit conversion and a 50 ms analog scan.
- Voltage and 4-20 mA measurement through the appropriate IOTA and jumper configuration.
- HART modems, open-wire detection and optional redundancy; exact -376 marking requires item-level matching.
The CC-PAIH02 high-level analog input function receives transmitter signals for Honeywell Experion Series C control. Manufacturer data specifies 0-5 V, 1-5 V and 0.4-2 V voltage ranges, plus 4-20 mA through a 250-ohm load path. The sixteen-channel module uses 16-bit conversion and scans analog inputs in 50 ms. Its documented features include HART communication, self-diagnostics, open-wire detection and optional redundancy. Digital HART information complements the analog measurement; the analog scan value does not define the completion time of every instrument communication transaction.
Terminations and channel modes must be selected as a system. CC-TAIX01/11 provides differential operation on channels 13-16, whereas CC-TAID01/11 supports differential channels 1-16; dedicated GI/IS use has its own IOTA requirements. Preserve input range, shielding, common reference, approved jumper arrangement and the configured control database when replacing hardware. This page retains 51405038-376 as the listed identifier, but the reviewed original tables do not explain that suffix or approve substitution by a -375 assembly. Verify the complete supplied label, hardware revision and receiving-system requirements before fitting the part.
The CC-PAIH02 51405038-376 Honeywell HART Analog Input Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell CC-PAIH02 51405038-376 official technical documentation and product links.
This multi-page Honeywell technical document contains the exact model and its technical data. Apply the values to the supplied type number and verify its revision before installation.
Select the configured range from the documented 0-5 V, 1-5 V, 0.4-2 V and 4-20 mA options. Current conversion uses the IOTA's 250-ohm load. Voltage inputs require the applicable jumper arrangement in the original installation instructions. Match engineering-unit scaling to the field transmitter; voltage capability is not permission to connect a thermocouple or RTD directly.
The model specification gives 70 dB common-mode rejection from DC to 60 Hz with a 500-ohm source imbalance, and 19 dB normal-mode rejection at 60 Hz. Common-mode voltage is limited to -6 to +5 V peak. These are qualified electrical limits, not immunity to any wiring fault. Follow the approved grounding, shielding and differential-input arrangement for the installed IOTA.
Compatible smart transmitters can supply HART information while their analog outputs are measured. Confirm the requested instrument variables and diagnostic reporting in the installed system. Check analog scaling and HART communication separately, and use the documented module and open-wire diagnostics during maintenance. A healthy analog reading alone does not establish correct digital communication.
