Honeywell 8C-PAINA1 Analog Input Module

Configured for high-density analog process measurement in Experion PKS distributed control environments, the Honeywell 8C-PAINA1 (8C-PAINA1 Analog Input Module) provides direct physical/electrical execution.

Hardware Specifications

4-20 mA HART Loop Protocol and DCS System Execution

The module processes 16 single-ended channels across standard 4 to 20 mA current loops using an integrated 250-ohm input resistance to convert analog signals into digital values via a high-resolution 16-bit analog-to-digital converter. Operating with a 50 ms loop scan rate, it provides channel-level galvanic isolation to prevent ground loops and protect internal controller electronics from transient field surges. Additionally, the circuitry supplies dedicated 24 VDC transmitter power per channel, eliminating the need for external marshalling power supplies while supporting online hot-swap insertion and removal within C300 controller nodes.

Frequently Asked Questions

Q: What is the loop scan rate and ADC resolution of the 8C-PAINA1 module?

A: The module executes a 50 ms loop scan rate and utilizes a 16-bit analog-to-digital converter (ADC) for precise signal conversion.

Q: Does the module provide field transmitter power internally?

A: Yes, the unit provides 24 VDC transmitter power per channel, which eliminates the requirement for external marshalling power supply infrastructure.

Q: Which I/O Termination Assemblies (IOTAs) are compatible with this module?

A: The module pairs directly with the 8C-TAIXA1 for non-redundant coated setups or the 8C-TAIXB1 for redundant coated terminal block configurations.

Field Installation Guidelines

• Ensure cabinet power is fully isolated before mounting or dismounting the 8C-PAINA1 module on its designated IOTA base.

• Verify that ambient operating temperatures and environmental controls align with standard Experion PKS DCS specifications.

• Route incoming 4 to 20 mA signal wiring through shielded twisted pairs, ensuring shield drains are grounded correctly to maintain galvanic isolation integrity.

• Confirm online hot-swap compatibility procedures and check that retention latches are fully engaged to secure backplane communication with the C300 controller.
