Product Overview
Brand: Yokogawa
Series: ADV151 Series – Digital Input Modules (24 V DC domain)
Model: ADV151‑E50/D5A00
The ADV151‑E50/D5A00 is a high‑density & high‑performance digital input module designed for industrial automation and process‑control systems. It belongs to the ADV151 family, which supports 24 V DC discrete input signals, with isolation and modular integration in back‑plane I/O racks. The suffix “E50” denotes a variant with SOE capture (Sequence‑of‑Events logging) built in, enabling detailed logging of discrete input transitions for diagnostic or event‑analysis purposes. The option code “/D5A00” refers to the module being supplied with the KS Cable Interface Adapter (ATD5A‑00) which simplifies connection of 32‑channel digital input wiring.
This module provides 32 separate channels for 24 V DC ON/OFF signals, isolated input circuitry, fast response, and rugged industrial footprint. It is ideal for large‑scale control systems, manufacturing automation, utilities, process plants and where discrete input logging and diagnostics are needed.

Applications
-
Collecting and processing 24 V DC discrete ON/OFF signals from field devices such as limit switches, selector switches, proximity sensors, and push‑buttons in manufacturing automation systems.
-
Integration into distributed control systems (DCS) or large modular I/O racks in process industries such as chemical, petrochemical, power generation, water/wastewater treatment, where high‑channel discrete input modules are required.
-
Use in redundant I/O rack/back‑plane configurations for high‑availability installations (e.g., safety systems, continuous process control) where uninterrupted discrete signal acquisition and logging are essential.
-
Monitoring machine interlocks, conveyor endpoints, operator panel buttons, safety door sensors and other discrete status points in automated production lines.
-
Facility and infrastructure automation: capturing discrete signals from electrical switchgear, alarms, lighting/HVAC panels, and integrating them into centralized control logic.
-
Retrofit or system expansion projects: replacing older discrete‑input modules with a modern high‑density module, retaining field wiring while enhancing diagnostics (SOE) and reducing rack footprint.
Advantages
-
High channel density: 32 discrete input channels in one module reduces rack space and wiring complexity – cost‑efficient for large point counts.
-
SOE capture capability: The “E50” variant supports sequence‑of‑events logging of discrete input transitions, improving diagnostics and event analysis in control systems.
-
Robust electrical isolation & noise immunity: With stand‑off voltages of 2 kV AC (input to system) and 500 V AC (between common groups) the module is built for industrial environments with high electrical noise.
-
Fast response time: With input response ≤ 8 ms and push‑button detection capability ~20 ms, the module supports both status monitoring and fast discrete logic.
-
Compact and lightweight: At ~0.30 kg and modest module dimensions, it simplifies installation and reduces system cabinet footprint.
-
Modular system integration: Designed to plug into back‑plane I/O racks, supporting system expansion, replacement and redundancy with minimal wiring changes.
-
Reliable brand ecosystem: Being part of the Yokogawa ADV15x series ensures long‑term support, spare availability and compatibility with other system modules.
-
Flexible wiring option: Supplied with a KS cable interface adapter per “/D5A00” option — simplifies field wiring and reduces installation time and error risk.
