製品紹介
The Yokogawa ADV142-S02 is a high-reliability Digital Input (DI) module engineered for demanding industrial applications within Yokogawa’s CENTUM VP and ProSafe-RS platforms. It is used to interface with external digital field devices, receiving discrete signals such as switch statuses, contact closures, or binary indicators.
This module supports 16 channels / voltage-free digital input, each optically isolated to prevent ground loop interference and signal degradation. The ADV142-S02 is particularly suited for applications where safety integrity and signal precision are critical, such as in Safety Instrumented Systems (SIS) or Emergency Shutdown (ESD) systems.
With its compact footprint, environmental resilience, and diagnostic features, the ADV142-S02 is an excellent choice for engineers seeking durability, integration flexibility, and long-term operational stability in digital input interfacing.
