Product Introduction

The Yokogawa ADV159‑P01 is a 32‑channel isolated digital input module designed for industrial automation and process‑control systems. It belongs to Yokogawa’s family of digital input modules and supports both contact (dry‑contact) and voltage input signalling, with push‑button/edge‑detection capability built‑in.

This module is engineered to receive discrete ON/OFF signals from field devices—such as limit switches, proximity sensors, push‑buttons, relay contacts—and convert them into logic signals for the control system. As a 32‑channel high‑density module with channel isolation, it is ideal for installations where many discrete points need reliable capture in one slot. The “P” in the suffix indicates push‑button input support, and “01” typically refers to the option code (e.g., ISA Standard G3 environment).

With fast response time, robust isolation, and compatibility with standard 24 V DC (and contact) input devices, the ADV159‑P01 works well in applications such as manufacturing automation, utilities, process plants, remote I/O racks and system expansions.

Technical Specifications

Applications

• In distributed control systems and field I/O racks the ADV159‑P01 captures ON/OFF signals from field devices—such as limit switches, float sensors, push‑buttons or relay contacts—and converts them into logic states for alarms, interlocks and sequence control.

• In manufacturing automation, the module monitors machine status inputs, operator panel push‑buttons, conveyor run/stop feedback, safety interlock signals and many other discrete states, providing high‑density acquisition in compact form.

• In process industries (petrochemical, oil & gas, power generation, water/wastewater) the module allows for large numbers of discrete input points with isolated channels, helping maintain signal integrity even in electrically noisy environments.

• In remote I/O nodes or expansions where wiring cost, panel space and installation time must be minimised, the ADV159‑P01 offers 32 channels in one module, reducing wiring, rack space and engineering effort.

• In retrofit or upgrade projects, the dual input‑type capability (voltage/contact) and push‑button support help integrate into existing field wiring infrastructure and support future expansions.

Advantages

1. High channel density – 32 discrete input channels in one module slot reduce the number of modules and overall footprint.

2. Flexible input types – Supports both contact and voltage input signals, enabling connection of a wide range of field devices.

3. Fast response & push‑button support – With ≤ 8 ms response and push‑button detection (≥ 20 ms ON, up to ~25 Hz), the module handles dynamic signals reliably.

4. Isolated channels for robustness – Channel isolation ensures minimal interference, strong immunity to ground loops and enhanced reliability in noisy industrial environments.

5. Compact and manageable weight – With approx. 0.40 kg weight and dimensions ~10.7 × 13.0 × 3.2 cm, the module is easier to install, service and replace.

6. Standardised 24 V DC compatibility – Aligns with common industrial discrete input signalling, simplifying integration and wiring.

7. Installation & wiring cost savings – With 32 channels per module and dual input‑type support, fewer modules and less wiring are needed.

8. Part of a proven modular field I/O ecosystem – Integration into Yokogawa systems ensures long‑term support, compatibility and reliability.
