Cold Junction Compensation and Channel-to-Channel Isolation
The AAT141-S00 S2 module incorporates dedicated channel-to-channel electrical isolation across all 16 input paths to prevent ground loop interference from corrupting low-level temperature signals. Onboard cold junction compensation (CJC) processing digitizes ambient variations at the terminal interface to correct thermocouple non-linearities in real time. The hardware architecture maintains a signal noise floor below 5 uVrms while supporting HART protocol pass-through for field instrument diagnostics.
Frequently Asked Questions
Q: What signal types can be wired directly to the AAT141-S00 S2 input channels?
A: The module accepts direct millivolt inputs ranging from -200 mV to +200 mV as well as standard industrial thermocouples requiring cold junction compensation.
Q: Does the AAT141-S00 S2 support HART pass-through communication on millivolt loops?
A: Yes, the module features integrated hardware compatibility for HART digital signal pass-through alongside analog sampling.
Q: What is the maximum acceptable signal noise level for incoming TC/mV measurements?
A: Onboard filtering maintains signal noise below 5 uVrms across the input span to preserve measurement accuracy.
Field Installation Guidelines
Ensure all 24 VDC power feeds are isolated prior to installing or removing the module. Mount the AAT141-S00 S2 on a standard 35 mm DIN rail, verifying that the rear locking clip engages completely to ensure mechanical stability. Route thermocouple and millivolt field wiring using twisted, shielded pairs, keeping signal conductors segregated from AC power lines by a minimum of 100 mm. Terminate all cable shields at a single chassis earth ground bus to suppress common-mode noise.

Tech & Buying Guide
Understanding Marshalling Cabinets in Industrial Control Systems Architecture
Industrial control system deployments rely on structured signal distribution to bridge field instrumentation with central processing hardware. A marshalling cabinet serves as the vital intermediate connection point between heavy field home-run multi-pair cables and delicate input/output (I/O) modules housed inside Programmable Logic Controller (PLC) or Distributed Control System (DCS) enclosures. By segregating field cable terminations from control hardware, engineers maintain system flexibility, safeguard controller components, and streamline commissioning workflows.
FAT vs SAT in Industrial Control Systems: Key Differences and Execution Guide
Industrial control system deployment relies on strict verification protocols to guarantee operational safety, system stability, and regulatory compliance. Commissioning complex Programmable Logic Controller (PLC) racks, Distributed Control Systems (DCS), and Safety Instrumented Systems (SIS) requires two critical milestones: the Factory Acceptance Test (FAT) and the Site Acceptance Test (SAT). Both procedures validate that system automation meets design specifications, but they occur at different stages of project execution and target distinct operational risks.
Hub vs Switch vs Router in Industrial Automation Architecture
Modern factory automation relies on reliable industrial networking infrastructure to exchange real-time field data across operational technology systems. Engineers often encounter networking hardware like hubs, switches, and routers when integrating Programmable Logic Controllers, Distributed Control Systems, and SCADA monitoring nodes. Although these devices share physical ports, they operate at different layers of the Open Systems Interconnection reference model and deliver distinct traffic management capabilities.
