Product Introduction

The ADV159‑P01 S1 is a high‑density isolated digital input module from Yokogawa’s field I/O range. It is designed to receive discrete input signals from the field — such as contacts, voltage input sensors, push‑buttons or switches — and feed them into an automation/control system.

The suffix “P01” indicates this variant supports push‑button input mode and includes the ISA Standard G3 option (“1” suffix). The “S1” suffix further denotes a particular configuration or form‑factor variant (for example I/O rack compatibility or special terminal block) though exact internal meaning may vary. With 32 input channels, isolated input architecture, fast response, and compact form‑factor, the ADV159‑P01 S1 is ideal for installations where many discrete signals must be handled reliably in one module slot, especially in factory automation, process control, utilities, and distributed I/O nodes.

It accepts standard 24 V DC discrete inputs (as well as contact inputs) with isolation between channels, supports push‑button/edge detection, and reduces wiring and panel space by providing multiple channels in a single unit. The module integrates into the modular I/O architecture to provide efficient, scalable discrete signal acquisition.

Technical Specifications

Applications

• The ADV159‑P01 S1 is used in distributed I/O racks within a DCS or automation system to gather many discrete ON/OFF signals from field devices (switches, sensors, push‑buttons, relays) and transfer them into the controller logic for monitoring, interlocks, alarms or sequence control.

• In manufacturing automation and machine control environments, the module monitors operator panel buttons, machine status sensors, conveyor run/stop feedback, safety interlocks and many other discrete signals in one compact package, allowing efficient wiring and panel space savings.

• In process industries (oil & gas, petrochemical, power generation, water/wastewater) the module handles large volumes of discrete inputs with high reliability, strong noise immunity (via isolation) and compact footprint—suitable for harsh or remote field nodes.

• In expansion or retrofit projects where many new discrete inputs must be added, the ADV159‑P01 S1 provides a scalable solution: 32 channels in one module, support for standard discrete wiring, and reduced module count, wiring cost and panel footprint.

• In systems requiring push‑button or operator input detection, edge counting or event capture of discrete signals in high‑density modules, this variant supports those functions while maintaining isolation and compactness.

Advantages

1. High channel density – With 32 inputs per module, the ADV159‑P01 S1 significantly reduces module count and wiring overhead compared with lower‑channel alternatives.

2. Dual input support (contact & voltage) – Accepts both dry‑contact and voltage input signals, giving flexibility in connecting different kinds of field devices without additional interface modules.

3. Fast signal detection – With a response time of ≤ 8 ms for status inputs and support for push‑button mode (min ON ~20 ms, max ~25 Hz cycle) the module is capable of detecting fast changing discrete events reliably.

4. Isolated channels for reliability – Each input channel (or channel groups) is isolated, which minimizes interference, ground loop issues and enhances signal integrity especially in noisy industrial environments.

5. Compact and moderate weight – At approx. 10.7×13.0×3.2 cm and ~0.40 kg the module is easy to handle, install and maintain in dense control racks or constrained panel spaces.

6. Standard 24 V DC compatibility – Works with widely‑used industrial 24 V DC discrete signals, facilitating integration with existing sensors and wiring infrastructure.

7. Wiring and installation efficiency – One module handles many signals, reducing panel space, wiring cost and installation time, which improves system scalability and maintenance.

8. Part of a proven field I/O ecosystem – Being part of Yokogawa’s module series ensures compatibility with I/O architecture, long‑term support and system integration ability.
