Product Description
The AAI835-S50 is a versatile hybrid analog interface module designed for the Yokogawa CENTUM VP Distributed Control System. This single-slot module integrates 4 analog input channels and 4 analog output channels, providing both sensing and actuation capabilities in a compact form factor.
Fully isolated channels ensure that field-side electrical noise or faults are contained, maintaining the integrity of the overall DCS network. Its hybrid design is particularly suitable for remote nodes or auxiliary control loops where space efficiency and multi-functionality are important.
Key Features
-
Hybrid Functionality: 4-channel 4–20 mA input + 4-channel 4–20 mA output in one unit
-
Full Galvanic Isolation: Each channel is electrically isolated for superior protection against ground loops and EMI
-
Standard Industrial Build: S50 configuration denotes a general-purpose, non-explosion-protected module
-
Flexible Interfacing: Supports pressure clamp terminals, MIL connectors, or KS1 cables for rapid deployment
Technical Specifications
| Item | Specification |
|---|---|
| Model Number | AAI835 |
| Dimensions (W × H × D) | 3.3 × 10.7 × 13 cm |
| Net Weight | 0.3 kg |
Industrial Applications
The AAI835-S50 is ideal for localized process control units, including:
-
Pump stations
-
Small-scale chemical reactors
-
Utility skids
By combining both input monitoring (e.g., pressure, flow) and output control (e.g., valve actuation) in a single module, it simplifies the architecture of auxiliary control loops within larger plant networks.
Technical FAQ
Q: Can the AAI835-S50 be used in redundant configurations?
A: Typically, this module is used in non-redundant applications for cost-effective localized control. For mission-critical loops requiring full failover, separate dedicated input and output modules are recommended.
Q: What cable is required for the MIL connector interface?
A: The MIL connector option is typically paired with the KS1 dedicated cable for direct connection to Yokogawa terminal boards or signal conditioners.
