Yokogawa A2SAM505-H000 S1 Current/Voltage Output Adaptor

Configured for analog current and voltage signal generation in the CENTUM VP N-IO network, the Yokogawa A2SAM505-H000 S1 (A2SAM505 Current/Voltage Output Adaptor) provides direct physical and electrical execution of isolated analog output functions. The adaptor interfaces with N-IO modules and converts internal control commands into configurable 0-10 VDC or 4-20 mA output signals while maintaining galvanic isolation between field circuits and the control system.

Channel Isolation and HART Output Integration

The A2SAM505 supports isolated analog output operation with channel-level galvanic separation between field-side wiring and the N-IO control domain. For current output operation, the adaptor supports HART 7 communication superimposed on the 4-20 mA loop, allowing simultaneous analog signal transmission and digital device communication. Open-loop monitoring is available during current output operation and activates when loop current falls to 0.65 mA or below.

Frequently Asked Questions

Q: Does the A2SAM505 require hardware jumpers to change between voltage and current output modes?
A: No. Output mode selection between 0-10 VDC and 4-20 mA is performed through system software configuration.

Q: Can the adaptor be replaced while the N-IO system remains energized?
A: The module is designed for hot-swappable operation when installed on the designated A2BN3D adaptor base plate and used according to Yokogawa maintenance procedures.

Q: What output load limitations apply to current mode operation?
A: The adaptor supports loads up to 750 Ohm at 20 mA output and up to 600 Ohm at 23 mA output while maintaining specified operating limits.

Field Installation Guidelines

• Mount the adaptor only on a compatible A2BN3D adaptor base plate.
• Verify field wiring polarity before energizing output circuits.
• Separate analog output cabling from high-energy power conductors to reduce conducted interference.
• Connect cable shields according to plant grounding standards and DCS cabinet grounding practices.
• Confirm field device loop resistance remains within the specified operating range before commissioning.
• Perform output verification using calibrated measurement equipment after installation or replacement.
• When HART communication is required, ensure loop components and field devices support HART-compatible operation.
