Product Overview

Brand: Yokogawa
Series: ADV14x Series – Digital Input Module Family
Model: ADV142-P12

The ADV142-P12 is one of the digital input modules designed for high-reliability industrial control and automation systems. It belongs to the ADV142 sub-family of the series, which supports 16 discrete input channels and accommodates higher voltage or special options compared to the base input modules. The suffix “-P12” designates a variant with particular configuration options (for example: “P” meaning pushbutton input support, “1” indicating a particular version or feature set, “2” indicating an enhanced temperature or diagnostic option).

This module is intended for systems that require capturing ON/OFF status of field devices — such as limit switches, proximity sensors, push buttons, contactors — and transmitting that information into a DCS or control system. With its robust design, the ADV142-P12 is suitable for manufacturing plants, process industries, utilities, power generation, and other automation-heavy environments where discrete signal reliability and noise immunity are critical.

Technical Specifications

Applications

• Monitoring field-device ON/OFF status in industrial automation systems, such as manufacturing lines, conveyors, machine interlocks.

• Integration into process-control systems (DCS) for capturing pump/motor/valve status in petrochemical, refining, power-generation or utility facilities.

• Use in redundant I/O rack systems where high availability is required (dual redundant configuration).

• Capture of push-button and selector-switch signals in operator panels, where discrete inputs are used for safety, control logic or emergency stop functions.

• Building and infrastructure automation: monitoring of discrete signals from HVAC, switchgear, lighting panels, fire-alarm systems.

• Retrofitting legacy automation systems: when migrating to newer I/O architecture while maintaining discrete signal capture capabilities.

Product Advantages

• High reliability and isolation: The module’s 2 kV AC isolation between input and system, and 1.35 kV AC between common groups, provide strong protection against electrical noise and surges.

• Broad voltage input capability: Being part of the ADV142 family, the module supports higher voltage AC digital signals directly without external converters.

• Compact and lightweight: At approximately 0.30 kg and modest physical size (~3.2 cm width), installation and maintenance are simplified, and rack-space impact is low.

• Pushbutton input support: The “P” option signifies capability to handle pushbutton input logic (e.g., edge counting) as well as simple ON/OFF status, increasing versatility.

• Wide temperature range: The suffix “2” implies an enhanced version capable of operation from –20 °C to +70 °C, making the module suitable for rugged or outdoor enclosures.

• System integration and redundancy: Compatible with back-plane based I/O systems and redundancy schemes, supporting high-availability automation architectures.

• Industrial grade durability: Designed for harsh environments, including high ambient temperature, high humidity, and electromagnetic interference conditions; and supports standard wiring methods for ease of service.

• Legacy and future-proof platform: As part of the ADV14x family, the module benefits from long field use, known compatibility, and support ecosystem.
