Product Description
The AAI135-S50/CCC01 is a high-reliability analog input module designed for the Yokogawa CENTUM VP distributed control system. It interfaces with 4–20 mA field transmitters and provides eight fully isolated input channels, ensuring that ground loops, noise, or voltage surges on one loop do not affect other channels or the system backplane.
This variant includes the CCC01 option, a protective connector cover that enhances mechanical stability and environmental protection at the wiring interface. The AAI135-S50/CCC01 is widely selected for applications where signal integrity, fault containment, and long-term reliability are critical.

Its fully isolated architecture makes it especially effective for long cable runs and mixed grounding environments.
Frequently Asked Questions
Does the AAI135-S50/CCC01 support HART communication?
No. The S50 suffix identifies a standard analog version without HART. For HART diagnostics and digital communication, the H50 or H53 variants should be selected.
What is the purpose of the CCC01 option?
The CCC01 connector cover provides added mechanical protection for the wiring interface, helping prevent accidental disconnection and improving durability in dusty or high-vibration environments.
