Product Description
The ASI133-H00/ATSA3S is a high-precision HART-enabled analog input interface designed for the Yokogawa CENTUM VP and Yokogawa ProSafe-RS automation platforms.
This module combines the ASI133-H00 analog input module with the ATSA3S pressure clamp terminal block, enabling reliable 4–20 mA signal acquisition from field transmitters while maintaining strong mechanical and electrical signal integrity.
As a HART-compatible device, the module supports bidirectional digital communication over the analog current loop, allowing engineers to perform:
-
Remote device diagnostics
-
Transmitter calibration
-
Predictive maintenance monitoring
Key reliability features include:
-
8-channel galvanic isolation architecture
-
Integrated transmitter loop power supply
-
Protection against electrical noise and ground loops
-
G3-rated corrosion resistance for harsh industrial environments
The ATSA3S pressure clamp terminal ensures gas-tight and vibration-resistant field wiring connections, improving long-term signal stability.

Technical FAQ
How does the ASI133-H00/ATSA3S handle HART data?
The module uses frequency-shift keying (FSK) modulation to overlay HART digital communication over the 4–20 mA analog signal. The digital data is forwarded to asset management software while maintaining continuous analog process measurement.
What is the advantage of the ATSA3S pressure clamp terminal?
The pressure clamp design provides constant mechanical tension on wiring conductors, improving reliability in environments with vibration, thermal cycling, or corrosive atmospheres compared to traditional screw terminals.
