Product Description
The Yokogawa AAI135-H00/K4A00 is an 8-channel isolated analog input module designed to acquire 4-20 mA current signals from field transmitters. It provides individual channel isolation, 10 ms data updates, and HART communication support. This configuration combines the HART communication option with a KS Cable Interface Adapter, making it suitable for analog signal acquisition in Yokogawa control systems.

Analog Input Function
The AAI135 receives 4-20 mA analog signals from field transmitters and converts them into input data for the control system. Its eight isolated input channels support individual signal acquisition while providing electrical isolation between input channels and the system.
Furthermore, the 10 ms data update period supports regular signal acquisition. The +/-16 uA accuracy and temperature drift specification provide reference values for evaluating measurement performance under the specified operating conditions.
HART Communication and Connection Configuration
The -H suffix identifies the digital communication option for the HART protocol. Therefore, this version supports HART communication in addition to its standard 4-20 mA analog input function.
The /K4A00 option specifies the KS Cable Interface Adapter (Model ATK4A-00). Meanwhile, the module documentation also identifies pressure clamp terminal blocks and other connection accessories as separate ordering options. These should not be confused with the K4A00 configuration.
Ordering Code Identification
| Code | Description |
|---|---|
| AAI135 | 8-channel isolated analog input module |
| -H | With digital communication (HART protocol) |
| 0 | Basic type |
| 0 | No explosion protection |
| /K4A00 | KS Cable Interface Adapter, Model ATK4A-00 |
Frequently Asked Questions
Q: How many analog input channels does the AAI135-H00/K4A00 support?
A: It supports eight isolated input channels, each accepting a 4-20 mA current signal.
Q: Does the AAI135-H00/K4A00 support HART communication?
A: Yes. The -H suffix identifies the HART digital communication option, in addition to the standard analog input function.
Q: What is the function of the K4A00 option?
A: K4A00 specifies the KS Cable Interface Adapter, Model ATK4A-00. It identifies the connection accessory configuration rather than an additional analog input function.
