Features:

  • AAI141-S00 provides 16 non-isolated 4-20 mA input channels with pressure clamp terminal connections.
  • Supports 2-wire transmitters with internal power or 4-wire transmitters requiring external power supply.
  • Compatible with ATA4S single or ATA4D dual-redundant terminal blocks for flexible system configuration.
The AAI141-S00 delivers 16 analog input channels in a single module, providing high-density signal acquisition for Yokogawa CENTUM VP and Stardom FIO systems. Each channel accepts standard 4-20 mA signals from field transmitters measuring pressure, temperature, level, or flow. The module uses pressure clamp terminals on ATA4S (single configuration) or ATA4D (dual-redundant configuration) terminal blocks, eliminating the need for screw-type terminations that can loosen over time. Pressure clamp terminals provide secure, vibration-resistant connections and reduce installation time. Recommended cable thickness is 0.5 to 2 mm² (AWG 20-14), with a peel-off length of 11mm without sleeve or 12mm with sleeve.

The AAI141-S00 supports both 2-wire and 4-wire transmitter connections, providing flexibility for various field device types. For 2-wire transmitters, the module provides loop power directly through the input channel, eliminating the need for external power supplies. This simplifies wiring and reduces panel space. For 4-wire transmitters, the module accepts a 4-20 mA signal from externally powered devices, requiring the user to provide separate field power. The input type is selected via setting pins on the associated terminal block or adapter.

The AAI141-S00 offers three distinct connection methods to accommodate different installation requirements. First, direct pressure clamp terminal connection using ATA4S (single) or ATA4D (dual-redundant) terminal blocks, ideal for standard panel installations. Second, terminal board connection using KS cable adapter ATK4A and KS1A cable to AEA4D terminal board, allowing remote mounting of field wiring from the I/O module.

The AAI141-S00 YOKOGAWA 16-Channel Analog Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

General

  • Manufacturer YOKOGAWA
  • Model AAI141-S00
  • Condition New Original ready stock
  • Product Family AAI143-S00 S1,AAI143-S50 S1,AAI143-S53 S1
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Oil & Gas: Upstream crude oil extraction, long-distance pipeline monitoring, and oil refinery process control.
  • Chemical & Petrochemical: Reactor temperature acquisition, pressure pipeline monitoring, and precise chemical flow metering.
  • Power & Energy: Boiler drum level control in thermal power plants, turbine monitoring, and utility water system control.
  • Water Treatment: Inlet/outlet flow rate, pH value, and turbidity data collection in water supply and wastewater treatment plants.
  • Overcurrent Protection: The internal current-limiting design allows a maximum input current of 27 mA. If a field transmitter faults and outputs excessive current, the module limits it automatically to prevent burning the internal sampling resistors.
  • Flexible 2/4-Wire Configuration: Each channel can be independently configured via hardware setting pins for 2-wire (module-powered) or 4-wire (externally powered) loops, preventing power conflicts and hardware damage.
  • Dual-Redundant Switching: Two AAI141 modules can be installed in adjacent slots to form a dual-redundant pair. If the active module fails, the system switches to the standby module within microseconds without disturbing the process.
  • Self-Diagnostics: The system continuously monitors the status of the A/D converter, microprocessor, internal voltage, and communication bus. When an anomaly occurs, the FAIL LED lights up, and a system alarm triggers on the DCS Human Interface Station (HIS).
  • Hot-Swapping: The module supports hot-swapping while the node unit (such as ANB10) is powered. Ensure the redundant module is healthy or the control loop is switched to manual/safe mode before replacement.
  • External Wiring Interface: The front interface connects to standard Yokogawa terminal boards (e.g., ATA4S, ATA4D) using dedicated KS signal cables (e.g., KS1).
  • Loop Resistance Matching: For dual-redundant configurations, the loop resistance of the signal cables must be strictly identical to maintain signal measurement accuracy.
  • Current State: The -S00 model is a standard type and does not support HART protocol communication.
Description
The AAI141-S00 is a 16-channel analog input module designed for Yokogawa CENTUM VP and Stardom FIO systems, accepting 4-20 mA signals from field transmitters. This non-isolated module supports both 2-wire and 4-wire transmitter connections, with terminal blocks ATA4S (single) or ATA4D (dual-redundant) available.

For 2-wire transmitter input, the AAI141-S00 provides transmitter power supply directly through the module. For 4-wire transmitter input, an external power source is required. When the AAI141-S00 power is off or abnormal, the current input loop is in an open state. 

The AAI141-S00 is part of a comprehensive I/O solution that includes analog input, analog output, and digital I/O modules. The AAI141-S00 pairs with ATA4S (single) or ATA4D (dual-redundant) terminal blocks, and can also connect via MIL cable directly to the module.

For signal wiring, the AAI141-S00 supports cable termination with or without sleeves. When using sleeves, it is recommended to use DIN 46228/1 (without insulating cover) or DIN 46228/4 (with insulating cover) sleeves.
