Product Description

The AAI143-S03/ATA4S-00 is a high-integrity 8-channel analog input module designed for the Yokogawa Centum VP and CS 3000 series. This module provides precise acquisition of 4–20 mA DC signals and is optimized for standard industrial applications. The S03 hardware style denotes Style 3, which features enhanced reliability, compact footprint, and high-speed data updates.

This variant includes the ATA4S-00 Pressure Clamp Terminal Block, enabling direct field wiring without the need for specialized external cabling. The module also incorporates an integrated transmitter power supply, supporting 2-wire loops while retaining flexibility for 4-wire (externally powered) devices via internal jumper settings. With 1500 V AC isolation, the AAI143-S03/ATA4S-00 safeguards the FCS backplane from field-side electrical disturbances.

Technical Specifications

Key Advantages

• Compact and flexible: Ideal for high-density I/O configurations where space is limited.

• High reliability: Full channel-to-system isolation protects remaining loops from faults.

• Simplified wiring: ATA4S-00 terminal block allows easy installation and replacement.

• Versatile field support: Can power 2-wire transmitters and accommodate 4-wire devices.

Frequently Asked Questions

Q: Is this module HART-enabled?
A: No. The S03 variant is standard analog input. HART communication requires the AAI143-H series.

Q: How does this differ from the 16-channel AAI143 modules?
A: The S03 hardware revision is an 8-channel module, designed for higher signal density in compact FIO node installations, whereas most AAI143 modules are 16-channel.

Q: Can the ATA4S-00 terminal block be removed?
A: Yes. The terminal block is modular and can be detached for wiring convenience or replacement.
