Product Introduction

The ADV161‑P00 is a high‑density digital input module designed for industrial control and automation systems. It belongs to Yokogawa’s field I/O module family and is tailored for applications requiring many discrete input channels captured reliably in one module slot.

With 64 input channels at 24 V DC discrete signal level (sink/source compatible), strong isolation, fast response, compact form factor and rugged industrial performance, this module is suited for distributed control systems (DCS), remote I/O racks, machine automation, utilities and plants where space, wiring cost and signal reliability matter.

The module supports standard ON/OFF discrete signals from field devices such as limit switches, proximity sensors, relay contacts, push‑buttons, operator panels and more. It converts them into digital logic for the control system, while offering robust protection against electrical noise, ground loops and harsh ambient conditions.

Because the ADV161‑P00 provides 64 input channels, it allows system designers to reduce module count, save panel space, minimize wiring termination points, streamline maintenance and improve scalability. It integrates cleanly into modular I/O architectures and enables efficient discrete‑signal acquisition for modern automation systems.

Technical Specifications

Applications

• In distributed control systems (DCS) and remote I/O racks, the ADV161‑P00 is used to capture large volumes of discrete ON/OFF signals from field devices such as limit switches, float sensors, proximity detectors, push‑buttons and relay contacts. These signals are forwarded to the control logic for monitoring, alarms, interlocking, sequencing and automation tasks.

• In manufacturing automation systems (e.g., machine lines, conveyors, packaging systems, operator panels), the module monitors many machine status sensors, operator panel buttons, run/stop inputs, safety interlock signals with high density in a single unit — saving panel space and wiring effort.

• In process industries such as oil & gas, petrochemical, power generation, water & wastewater treatment, utilities, the ADV161‑P00 supports high‑channel discrete input capture in harsh ambient and noisy electrical environments, thanks to strong isolation and rugged temperature/humidity ratings.

• In redundant or high‑availability I/O architectures, the 64‑channel module reduces module count and supports system reduction of slot count, wiring termination points and simplifies maintenance while enabling scalability.

• In system expansions or retrofits where many additional discrete input points must be added but panel space and wiring cost are constrained, this module offers a cost‑effective, compact, high‑density solution with standard 24 V discrete inputs and field‑wiring compatibility.

Advantages

1. High channel density — With 64 input channels in one module, the ADV161‑P00 reduces the number of modules required, minimizes cabinet footprint and lowers wiring/termination complexity.

2. Standard 24 V DC discrete interface — Compatible with common industrial ON/OFF field devices and sensors, reducing need for special interface modules or signal conversion.

3. Fast and reliable response — Response time ≤ 8 ms and support for push‑button/edge detection (min ON ~20 ms, up to ~25 Hz) means timely capture of discrete events.

4. Robust electrical isolation and noise immunity — Built‑in 2 kV AC isolation between input signal and system, and 500 V AC between groups of channels, ensures stable operation in electrically harsh environments.

5. Compact size and moderate weight — At approximately 220 × 155 × 35 mm and ~0.30 kg, the module fits into dense I/O racks and simplifies installation and maintenance.

6. Scalable and future‑proof — High‑density input supports system expansions, higher I/O counts and future growth without large increases in modules or wiring complexity.

7. Reduced maintenance and wiring cost — Fewer modules, fewer termination points and standardized signal interface translate to lower wiring cost, faster commissioning and easier service.

8. Proven field I/O platform — Being part of Yokogawa’s module family ensures compatibility, reliability and long lifecycle support for automation systems.
