Product Overview
Brand: Yokogawa
Series: ADV14x Series – Digital Input Modules
Model: ADV142‑S03
The ADV142‑S03 is a digital input module designed for industrial automation and control systems, forming part of the ADV142 sub‑family which handles high‑voltage AC discrete inputs. The “S03” suffix indicates a specific variant of the ADV142 family with enhanced or particular features (for example: “S” could denote a special environment or connector version, “03” a particular revision).
This module is intended to convert ON/OFF signals from field devices (switches, push‑buttons, contacts) into digital logic signals that the control system can process. The module supports robust isolation, wide operating conditions, and compatibility with modular I/O rack architectures, making it suitable for process plants, manufacturing automation, utilities and other demanding control installations.

Applications
-
Monitoring discrete ON/OFF field signals in automation systems (200‑240 V AC) such as limit switches, selector switches, pushbuttons.
-
Integration into distributed control systems (DCS) / modular I/O racks in process plants: power generation, petrochemical, chemical, refining.
-
Suitable for redundant I/O arrangements where high availability is required, capturing status data reliably.
-
Use in manufacturing automation lines for machine interlocks, conveyor status, operator panel inputs.
-
Building infrastructure and facility automation: capturing high‑voltage AC discrete signals from large switchgear, HVAC systems, electrical panels.
-
Retrofitting or expansion scenarios requiring discrete AC input modules with modern I/O standards and isolation performance.
Advantages
-
High‑voltage AC input capability: The module supports 200‑240 V AC discrete inputs directly, reducing need for external signal conditioning.
-
Robust isolation and noise immunity: Withstanding voltages of 2 kV AC (input ↔ system) and 1.35 kV AC (between commons) help ensure signal integrity and system safety.
-
Compact and lightweight: At approximately 0.26 kg and slim profile, it saves rack space and eases handling/installation.
-
Wide ambient tolerance: Operating from –20 °C to +70 °C (for the enhanced “S03” version) makes it suitable for harsh industrial or semi‑outdoor installations.
-
System integration ready: Designed for back‑plane modular I/O systems, enabling plug‑in style replacement or expansion with minimized downtime.
-
Proven field performance: Part of a well‑established series, offering reliability in industrial environments with switching noise, vibration and thermal stress.
-
Versatile discrete input capture: Supports both status detection and, in variants, pushbutton edge counting, giving flexibility in how field signals are handled.
-
Maintenance friendly: Standard module footprint and replacement ease reduce service time and complexity in critical systems.
