Product Overview

Brand: Yokogawa
Series: ADV14x Series – Digital Input Modules
Model: ADV142-S02

The ADV142-S02 is a 16-channel digital input module designed for high-reliability industrial automation systems. It belongs to the ADV142 family, which is targeted at AC digital input for higher voltage ranges and robust I/O applications in distributed control systems (DCS) or process automation racks. The “S02” suffix identifies a specific variant with options tailored for the module in this series (for example ambient temperature range, diagnostics, connector type).

This module is engineered to accept field ON/OFF signals (typically 200–240 V AC in this family) and convert them into logic signals for the control system with strong electrical isolation, high noise immunity and compact form factor. It is well suited to process plants, manufacturing, utilities, power generation, building automation and other demanding automation environments where discrete input reliability is essential.

Technical Specifications

Note: Some values are typical for the ADV142 family and may vary slightly depending on the exact “S02” variant.

Applications

• Capturing 200–240 V AC discrete ON/OFF signals from field devices such as limit switches, selector switches, sensor outputs, pushbuttons in manufacturing lines and automation systems.

• Integration into DCS or control-rack systems in process industries (petrochemical, chemical, oil & gas, power generation) where discrete high-voltage signal monitoring is required.

• Use in redundant I/O rack systems supporting high availability and critical process monitoring.

• Monitoring operator panel signals, safety interlocks, status indications in industrial automation and large machinery installations.

• Building automation and facility management scenarios, where switchgear, large HVAC panels or electrical panels provide high-voltage discrete status signals to the automation system.

• Retrofit or upgrade projects where higher-voltage AC discrete inputs need to be integrated into modern I/O architectures.

Advantages

• High-Voltage AC Digital Input Support: As part of the ADV142 family this module supports high-voltage AC discrete input signals directly, eliminating the need for external signal converters.

• Strong Electrical Isolation & Noise Immunity: Withstanding voltages of 2 kV AC between input and system, and 1.35 kV AC between common groups, the module offers robust protection in electrically harsh environments.

• Compact & Lightweight Form Factor: At approximately 0.26 kg and slim width (~3.2 cm) the module saves cabinet space and simplifies replacement or maintenance.

• Wide Ambient Temperature Range: The “S02” variant is rated for -20 °C to +70 °C, making it suitable for industrial or semi-outdoor enclosures.

• Versatile Integration: Designed for modular rack/back-plane systems, with standard field wiring connection methods, easing installation and servicing.

• Reliable Field Performance: Built for demanding conditions including vibration, switching noise, and high ambient temperatures, delivering consistent discrete input acquisition.

• Scalable Architecture: As a 16-channel module in the ADV14x family, it allows scalable system architecture and easier expansion or replacement.

• Serviceability: Standardised module dimensions and connector types support quick swap-out, reducing downtime in critical installations.
