Features:
- Full Channel-to-Channel Isolation for Signal Integrity
- Built-in Transmitter Power Supply Simplifies Field Wiring
- Fast 10ms Data Update for Real-Time Control
The YOKOGAWA AAI143-S53 S1 provides complete isolation between input channels and between inputs and the system. This design eliminates ground loops, prevents cross-channel interference, and ensures accurate measurement even in electrically noisy industrial environments, reducing troubleshooting time and improving system reliability.
Each channel of the YOKOGAWA AAI143-S53 S1 can power a 2-wire transmitter directly, delivering 19.0V at 20mA with overcurrent protection. This eliminates the need for external power supplies for most field devices, reducing cabinet space, wiring complexity, and overall installed cost.
With a 10ms data refresh rate and 100ms step response time, the YOKOGAWA AAI143-S53 S1 is optimized for fast-responding control loops. This ensures that critical process variables are updated quickly, enabling tighter control and faster alarm response in applications such as flow and pressure regulation.
The AAI143-S53 S1 YOKOGAWA solated 16-Channel 4-20mA Analog Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Refineries and Petrochemical Plants – Monitors 4-20mA signals from pressure, temperature, and flow transmitters in critical process units.
- Power Generation – Acquires analog signals from boiler controls, turbine monitoring, and emissions systems with high noise immunity.
- Water and Wastewater Treatment – Connects to level, pH, and flow sensors across distributed pump stations and treatment trains.
- Oil & Gas Offshore Platforms – Provides reliable, isolated input channels in corrosive environments (ISA G3 option included), reducing maintenance from salt and humidity.
- No Zener Barrier Permitted – For intrinsic safety, the module requires an isolation barrier, not a Zener barrier, as clearly specified in Yokogawa documentation.
- Withstanding Voltage – Rated at 1500V AC for 1 minute between input and system, ensuring operator and equipment safety during fault conditions.
- ISA Standard G3 Option (Suffix 3) – The S53 version includes corrosion resistance protection, making it suitable for harsh atmospheres with airborne contaminants.
- Redundancy for Process Safety – Dual-redundant configuration support allows the module to be used in control loops that require high availability, reducing the risk of unplanned shutdowns.
- No Field Firmware Updates for Base Function – The module's core analog input function is hardware-based and does not require user-applied firmware updates.
- HART Communication Requires EB401 Update – To enable HART on this module, ensure the ER bus node unit's EB401 firmware is revision 2 or later.
- Compatible Control Software – Works with LFS1700 (AFV30/40), LFS1500 (AFV10), LFS1300 (AFS30/40), LFS1330 (AFG30/40/8), and LFS1350 (AFF50) control functions.
- Engineering Environment – Configured using Yokogawa's Standard Builder Function (LHS5100/LHMS5100); no separate module-specific firmware tool is required.
