Description
The Honeywell 8C-PAINA1 (51454470-175) is a 16-channel, single-ended analog input module designed for the Honeywell Experion PKS Series 8 and Experion LX control systems. This module provides reliable acquisition of 4–20 mA DC process signals from field transmitters, converting them into digital values for high-speed process control. As a key component of the Series 8 I/O architecture, it integrates directly with the I/O Termination Assembly (IOTA) to streamline installation and reduce marshalling requirements.
Features
- 16-channel single-ended analog input capability
- Integrated on-board excitation power for field transmitters
- Supports optional redundancy when paired with a compatible IOTA
- Extensive self-diagnostics for channel integrity and module health monitoring
- Hot-swappable design for online maintenance without system shutdown
- Conformal coated (G3-rated) for harsh industrial environments
Applications
- Oil & Gas: Monitoring of pressure switches, gas alarms, and safety valve status.
- Power Generation: Tracking turbine interlocks and generator trip signals.
- Chemical Processing: Managing reactor batch states and safety interlocks.
- Water/Wastewater: Supervising pump status and critical utility alarms.

Installation Guidelines
- Mount the module onto a compatible Series 8 IOTA (e.g., 8C-TAIXA1 or 8C-TAIXB1).
- Ensure the system is powered down if required by local safety protocols, though the module supports hot-swapping.
- Use shielded twisted pair (STP) cabling for all analog signals.
- Route signal cables away from high-EMI/RFI sources to maintain signal integrity.
- Verify field power selection (internal vs. external) via the IOTA configuration before applying power.
- Handle with standard ESD precautions to prevent damage to sensitive electronic components.
FAQ
What is the 8C-PAINA1?
The Honeywell 8C-PAINA1 is a 16-channel, non-HART analog input module for the Honeywell Series 8 I/O platform, used in Experion PKS and Experion LX systems.
Does it power the field devices directly?
Yes, it provides transmitter field power through the associated I/O Termination Assembly (IOTA), eliminating the need for external marshalling power supplies.
Does the 8C-PAINA1 support HART communication?
No, this is a non-HART module. For HART-compatible analog inputs, please refer to the 8C-PAIHA1 model.
Can modules be removed or inserted while powered?
Yes, the module supports hot-swapping, allowing for maintenance and replacement without shutting down the control system.
