Brand: Yokogawa
Series: ADV151 Series – Digital Input Modules (24 V DC domain)
Model: ADV151‑H50/D5A00
The ADV151‑H50/D5A00 is a digital input module from the ADV151 family, designed for industrial automation systems requiring high reliability and discrete signal acquisition. The “H50” suffix indicates a variant tailored for heavy‑duty or higher‑current input channels (H = higher drive or heavy load) within the ADV151 32‑channel platform. The “/D5A00” option denotes the module has a KS Cable Interface Adapter for simplified wiring. This module supports 24 V DC ON/OFF discrete input signals, fits into modular I/O racks/backplane installations, and is suitable for manufacturing, process, utilities and infrastructure systems.

| Typical input current per channel | Approx. 4.1 mA ±20% (at rated voltage) |
| Maximum allowable input voltage | 30.0 V DC |
| Withstanding voltage (input ↔ system) | 2 kV AC for 1 minute |
| Withstanding voltage (between commons – every 16 channels) | 500 V AC for 1 minute |
| Input response time (status input) | ≤ 8 ms |
| Minimum ON detection time (push‑button input mode) | ~20 ms |

Collecting and monitoring 24 V DC discrete ON/OFF signals from field‑devices such as selector switches, limit switches, push‑buttons, proximity sensors in manufacturing automation lines.
Integration into distributed control systems (DCS) or modular I/O rack/backplane installations in process industries (chemical, petrochemical, power generation, utilities) where high‑density discrete input monitoring is needed.
Use in machine automation: monitoring safety interlocks, conveyors, operator panel signals, emergency stop circuits.
Building/infrastructure automation: capturing status signals from switchgear panels, alarms, facility controls, lighting/discrete systems in large buildings or campuses.
System retrofit or expansion: replacing older discrete‑input modules with modern high‑density modules that provide identical 24 V DC input domain but improved reliability and wiring convenience.
High channel density: 32 channels in one module reduce wiring, save panel space, and simplify I/O architecture.
Robust electrical isolation and noise immunity: With 2 kV AC isolation from input to system and 500 V AC between commons, the module is built to operate in industrial environments with electrical noise.
Fast response time: ≤ 8 ms detection ensures timely capture of discrete events; push‑button mode (~20 ms min detection, up to 25 Hz) supports dynamic applications.
Compact and lightweight: At ~0.30 kg and modest dimensions, the module is easy to install, maintain and replace.
Modular system integration: Designed for plug‑in backplane or rack mounting, enabling straightforward system expansion or replacement.
Improved wiring convenience: With the “/D5A00” interface adapter option, field wiring is simplified, reducing installation time and error risk.
Wide ambient tolerance: The –20 °C to +70 °C operating range allows deployment in a variety of industrial environments, including those without climate‑controlled enclosures.
Brand and ecosystem reliability: Being part of the Yokogawa ADV151 series ensures compatibility with existing installations, long service life and spare‑parts support.
