Each channel is independently isolated, preventing ground loops and minimizing signal interference between channels for improved measurement accuracy.
High-Density Data Acquisition
Compact module design allows efficient use of I/O space, reducing cost per channel in large-scale automation systems.
Versatile Field Compatibility
Supports a wide range of 4–20 mA transmitters, making it suitable for applications across oil & gas, power generation, and water treatment industries.
FAQs
Does the ASI133 support 2-wire transmitter power?
Yes, the module provides loop power for 2-wire transmitters, allowing both power and signal transmission over a single pair of wires.
Can this module operate in hazardous environments?
Yes, it is certified for use in hazardous areas (IEC, ATEX) and can be safely deployed when installed according to the relevant safety guidelines.
How do I verify communication status?
Front-panel LED indicators provide status information. A steady green LED confirms proper operation and communication with the Field Control Station.
Is the ASI133 compatible with HART communication?
Standard versions focus on 4–20 mA signals. For HART compatibility, verify the specific model variant or suffix before deployment.
