Product Description

The A2SAM105-H000 (A2SAM105) is a high-specification analog input adapter for the Yokogawa Electric Corporation CENTUM VP N-IO (Network I/O) subsystem. It converts 4–20 mA or 1–5 V signals from field transmitters into digital data for the control network, with each channel configurable via software for maximum flexibility.

Designed for mission-critical and safety-instrumented systems (SIS), the A2SAM105-H000 supports Triple Modular Redundancy (TMR) architectures to meet SIL3 safety requirements. The module natively supports HART 7 for advanced asset management and remote calibration. Its compact baseboard-mounted design includes robust self-diagnostics that monitor both internal hardware health and external loop integrity, including wire breakage and short circuits.

Technical FAQ

Can the A2SAM105-H000 be used in ProSafe-RS safety systems?
Yes. It is fully compatible with Yokogawa ProSafe-RS SIS for emergency shutdown (ESD) and fire & gas (F&G) applications.

Does this adapter provide power to 2-wire field transmitters?
Yes. The module can supply loop power to standard 2-wire 4–20 mA transmitters directly from the N-IO baseboard, simplifying cabinet wiring.
