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

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.
