Product Description
The AAI143-H00/A4S00 is a 16-channel high-density analog input module designed for Yokogawa CENTUM VP and CS 3000 control systems. It interfaces with 4–20 mA DC signals from field transmitters and features HART digital communication, enabling the control system to access diagnostics and maintenance data from intelligent instruments without additional hardware.
This variant includes the /A4S00 option, which provides a factory-installed ATA4S-00 Pressure Clamp Terminal Block for secure, direct field wiring without specialized connector cables. Each channel is configurable via internal pins to support either 2-wire (loop-powered) or 4-wire (self-powered) transmitters. With 1500 V AC isolation and low thermal drift, the module ensures accurate and reliable signal acquisition in demanding industrial environments.

Frequently Asked Questions
Q: Can this module support self-powered (4-wire) transmitters?
A: Yes. Each channel can be individually configured via internal pins to support either 2-wire (loop-powered) or 4-wire (self-powered) devices.
Q: What is the maximum current the module can supply to a field transmitter?
A: The transmitter power supply is limited to 25 mA per channel to protect the circuitry.
