Product Overview

Brand: Yokogawa
Series: ADV151 Series – Digital Input Modules (24 V DC domain)
Model: ADV151‑E50

The ADV151‑E50 is a 32‑channel digital input module designed for industrial automation and control‑system environments. It accepts discrete 24 V DC ON/OFF signals from field devices (such as switches, sensors, push‑buttons) and converts them into logic‑level data that the control system uses. It offers isolated channels, supports SOE (Sequence of Events) capture, and is built for high reliability in automation environments. As part of the ADV151 family, it provides high channel density, modular rack/back‑plane mounting, and is well suited for large distributed control systems (DCS) and plant‑wide installations.

Technical Specifications

Applications

• Capturing 24 V DC discrete ON/OFF status signals from field devices (such as selector switches, limit switches, push‑buttons, relay contacts) in manufacturing automation lines and process plants.

• Integration into distributed control systems (DCS) and I/O rack/back‑plane modules in large‑scale industrial environments (chemical, petrochemical, power generation, utilities) where high‑channel discrete input modules are required.

• Use in redundant I/O rack configurations for high‑availability systems where uninterrupted signal acquisition is critical (e.g., safety systems, critical alarms).

• Machine automation: monitoring interlocks, conveyor end‑positions, operator panel signals, safety door switches, and other discrete status points in production environments.

• Building automation and infrastructure control: capturing discrete signals from switchgear panels, facility alarms, lighting control, HVAC discrete inputs, large building systems.

• Retrofit or upgrade projects: replacing older discrete input modules with modern high‑density digital input modules, while preserving field wiring and signal types.

Advantages

• High channel density: With 32 channels per module, the wiring and rack footprint are optimized compared to lower‑channel modules.

• Robust electrical isolation & noise immunity: With 2 kV AC isolation between input and system circuits, and 500 V AC between common groups, the module supports reliable operation in electrically noisy industrial environments.

• Fast response & support for push‑button logic: With response times ≤ 8 ms and push‑button detection (≈ 20 ms ON detection, cycle up to 25 Hz), the module supports both status and fast discrete input logic.

• Compact and lightweight: At approximately 12.7 cm × 2.5 cm × 12.7 cm and ~0.30 kg weight, the module is easy to install and maintain, reducing cabinet space and handling burden.

• Modular system integration: Designed for plug‑in back‑plane installations and compatible with modular racks, enabling simple expansion or replacement with minimal wiring changes.

• Wide ambient tolerance and ruggedness: Built to endure industrial ambient conditions, including temperature extremes and harsh wiring environments.

• Proven brand reliability and ecosystem: As part of Yokogawa’s ADV15x series, the module benefits from field‑proven performance, spare‑part availability, and long‑term support.

• Flexible wiring options: Supports both clamp‑type terminals and dedicated connector cables, providing flexibility for field wiring and installation.

• Cost‑efficient upgrade path: Because the module supports modern digital input requirements and high channel count, its use helps future‑proof discrete input architecture.
