Technical Overview
The A2SAM105-H000 S2 is a high-precision signal conditioning adaptor for Yokogawa N-IO (Network I/O) field units. This Style 2 (S2) module converts field-side analog signals—4–20 mA current loops or 0–10 V DC voltage signals—into a standardized format for the DCS. With integrated HART communication, it allows simultaneous process monitoring and remote device configuration, supporting smart instrumentation management in modern industrial automation systems.

Technical FAQ
Can this adaptor be used with 4-wire transmitters?
-
Yes. 4-wire transmitters can be connected using the signal input pins, bypassing the internal 24 V supply. Proper wiring at the terminal base is required.
What are the benefits of the Style 2 (S2) revision?
-
Updated internal semiconductors improve thermal dissipation and long-term stability in high-temperature industrial cabinets.
Does the -H suffix support all HART versions?
-
Yes. It supports HART 5, 6, and 7 device variables for comprehensive asset management and diagnostics.
