Product Overview
Brand: Yokogawa
Series: ADV14x Series – AC Digital Input Modules
Model: ADV142-P03
The ADV142-P03 is a 16-channel AC digital input module designed to handle high-voltage AC ON/OFF signals in industrial control systems. It belongs to the ADV14x family of modules targeted at DCS (Distributed Control System) environments and process automation setups. The “142” designates the module variant that supports 200 to 240 V AC input, while the suffix “-P03” identifies specific options: “P” indicates pushbutton-input type functionality, “0” indicates a general-purpose variant, and “3” indicates the enhanced versions with ISA G3 standard option and wide operating temperature range (-20 °C to +70 °C).
This module is engineered for rugged industrial environments — capable of capturing status of field devices (limit switches, pushbuttons, contacts) and delivering reliable signals into the control system with high isolation, robust wiring support and compatibility with redundant system architectures. It is suitable for process plants, manufacturing lines, power generation, utilities, petrochemical installations, and other automation applications where AC digital signal inputs must be monitored.

Applications
-
Monitoring AC-powered field devices such as control panel pushbuttons, limit switches, selector switches in manufacturing and automation systems.
-
Integration into process control systems (DCS) for capturing status information of pumps, valves, motors, breakers and instrumentation in power plants and utilities.
-
Use in petrochemical, chemical, refining operations where high-voltage AC signals must be reliably converted into the automation system.
-
Suitable for redundant system architectures where dual-redundant I/O modules are required for high reliability.
-
Building automation and energy management systems where AC signal monitoring is required (e.g., large electrical switchgear panels, HVAC controls).
-
Retrofitting older installations that operate on higher AC voltages (200-240 V) and require modern I/O modules to interface with modern control systems.
Product Advantages
-
High-voltage compatibility: Designed to accept 200-240 V AC signals directly, eliminating need for external voltage converters.
-
Robust isolation and surge protection: 2 kV AC isolation between input and system, 1.35 kV AC between commons ensures reliable performance in electrically noisy industrial environments.
-
Wide operating temperature: With “3” suffix variant able to operate between –20 °C and +70 °C, it is well suited for harsh indoor/outdoor installation.
-
Pushbutton input functionality: The “P” option supports pushbutton edge counting, making it flexible not just for status detection but for operator-interface signals.
-
Compact and lightweight: At ~0.30 kg and small module dimensions, installation is space-efficient and maintenance/replacement is easier.
-
Redundancy friendly: Capable of operation in dual-redundant I/O racks, supporting high-availability system architectures.
-
System integration: Seamless compatibility with automation and DCS system backplanes, enabling standardized wiring, diagnostics and maintenance.
-
Durability: Heavy duty design for industrial use; accommodates AC signal variations, high isolation and long service life.
