Product Overview
Brand: Yokogawa
Series: ADV14x Series – Digital Input Module
Model: ADV142
The Yokogawa ADV142 is a high-performance AC Digital Input Module designed for distributed control systems (DCS) and industrial automation environments.
It is an upgraded version of the ADV141 series, specifically engineered to accept 200 V AC to 240 V AC digital input signals across 16 isolated channels.
The module converts external AC ON/OFF signals into logic-level data that can be processed by a control system, providing secure and reliable monitoring of plant equipment status.
ADV142 modules feature strong electrical isolation, surge protection, and superior noise immunity, making them suitable for harsh process-control conditions such as power generation, petrochemical operations, and heavy industrial machinery control.
