Yokogawa A2SAM105-H000 Current/Voltage Input Adapter

Configured for analog signal acquisition in CENTUM VP platforms, the Yokogawa A2SAM105-H000 (A2SAM105 Current/Voltage Input Adapter) provides direct physical/electrical execution. The hardware conditions current and voltage signals across baseboard-mounted N-IO nodes to execute real-time telemetry recording and process control loops.

Channel-to-Channel Isolation & Cold Junction Compensation

The A2SAM105-H000 implements galvanic channel-to-system isolation rated up to 1500 VAC, preventing ground loops and suppressing high-frequency common-mode noise across industrial field wiring. Each input channel supports individual software configuration to seamlessly transition between 4-20 mA DC current loops and 1-5 V DC voltage inputs. Internal analog front-end circuitry utilizes dynamic cold junction compensation (CJC) algorithms and high-precision analog-to-digital converters to maintain a +/-0.1% span accuracy across operational thermal ranges. Furthermore, integrated field loop diagnostics detect open-circuit wire breaks and out-of-range signal conditions before feeding digitized values to the CENTUM VP control bus.

Frequently Asked Questions

Q: How does the A2SAM105-H000 handle signal input switching between current and voltage modes?

A: Technicians configure each channel independently via the software environment. The internal multiplexing circuit routes the input through either an internal 250 ohm precision sense resistor for 4-20 mA DC current loops or a high-impedance (>= 2 Mohm) attenuator stage for 1-5 V DC voltage signals without requiring physical jumper modifications on the module board.

Q: Can the A2SAM105-H000 adapter be hot-swapped during active system operations?

A: Yes, the adapter supports hot-swapping on baseboard-mounted N-IO units. However, field engineers must ensure the redundant baseboard backplane remains powered and active. Furthermore, removal of the module in a simplex configuration will interrupt signal acquisition for all 16 channels, whereas a TMR or dual-redundant setup automatically switches execution to the backup module with zero latency.

Field Installation Guidelines

Engineers must mount the A2SAM105-H000 directly onto a compatible Yokogawa N-IO baseboard slot, ensuring the locking mechanisms fully engage with the backplane connectors. When wiring field signals, installers must route shielded twisted-pair cables through grounded cable glands and land the shield braids on designated cabinet earth buses to avoid noise coupling. Always maintain a minimum bend radius for incoming field harnesses and verify that 24 VDC auxiliary loop power supplies are switched off prior to terminal block landings. Ensure cabinet ambient temperatures remain between 0 and 55 deg C with adequate convection airflow to prevent thermal throttling.
