Product Introduction
The Yokogawa ADV142-S03 is a robust and reliable Digital Input Module designed for seamless integration into Yokogawa’s CENTUM VP and ProSafe-RS control systems. It is built to acquire discrete input signals from field devices such as limit switches, pushbuttons, and contact closures. With 16 isolated input channels, the ADV142-S03 ensures high signal fidelity and operational safety, making it ideal for both process control and safety instrumented systems.
Engineered for environments requiring strict safety and performance standards, the module offers galvanic isolation per channel to prevent electrical noise and ground loop issues. Its compact design supports efficient cabinet space use while maintaining ease of maintenance with clear LED status indicators for each input channel. The ADV142-S03 is compliant with international standards and suitable for use in hazardous locations when combined with Yokogawa’s ProSafe-RS system.
