Features:
- Robust AC Input Handling
- Enhanced Safety with Hazardous Area Certification
- Superior Electrical Isolation
The Yokogawa ADV141-S12 directly accepts 100-120 V AC signals, eliminating the need for bulky interposing relays. This direct coupling reduces installation complexity and points of failure, offering a reliable interface between your DCS and standard AC field devices.
Certified for Class I, Division 2 (Groups A,B,C,D) locations, this module can be safely installed in environments where flammable materials exist. The Non-Incendive design ensures that under normal or abnormal operating conditions, the module will not ignite the surrounding atmosphere.
Featuring 2 kV AC isolation between the input signal and the system bus, the Yokogawa ADV141-S12 effectively blocks ground loops, electrical noise, and voltage spikes. This protects the central controller from field-side disturbances, ensuring stable and accurate data acquisition.
The ADV141-S12 Yokogawa AC Digital Input Modules may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
