Yokogawa Electric Corporation ADV151-P63 Digital Input Module

The Yokogawa ADV151-P63 Digital Input Module provides 32 discrete digital inputs for real-time status monitoring in CENTUM DCS installations, converting field-device ON/OFF signals into digital data for DCS processing. It expands input capacity, replaces failed I/O modules, and supports reliable status monitoring in process control systems, typically installed in Yokogawa CENTUM cabinets and control panels. Key specifications include a 24 VDC rated input (sink/source), input ON 18–26.4 VDC, input OFF ≤5 VDC, and approximately 4.1 mA per channel with a maximum input voltage of 30 VDC. Channel-to-system isolation is approximately 2 kV AC withstand, and the module features a response time of ≤8 ms with dual redundant system configuration. Operating temperature range is -20°C to 70°C (G3 option). Common applications include monitoring discrete signals from switches, relays, and contact devices in oil & gas, power generation, and manufacturing environments to detect valve positions, motor states, and alarm conditions. Common replacements include ADM12C, ADV151-P53, and ADV161 Digital Input Module.
