Yokogawa ADV157-S00 CENTUM VP 32-Channel Digital Input Module

Product Overview

The Yokogawa ADV157-S00 functions as a high-density digital input interface within the CENTUM VP architecture. This module captures field data from up to 32 isolated channels, specializing in status monitoring, pushbutton edge detection, and digital counting operations. It converts 24 V DC field signals into system-level logic, allowing the controller to track machine states and pulse-based metrics with high precision.

Technical Specifications

The ADV157-S00 provides robust signal acquisition via the following parameters:

• Channel Count: 32 isolated digital input channels

• Primary Functions: Status Input, Pushbutton Edge Detection, Counting

• Rated Input Voltage: 24 V DC

• Input ON Voltage Range: 18.0 to 26.4 V DC

• Input OFF Voltage: ≤ 5.0 V DC

• Input Current: 4.1 mA (±20%) per channel @ 24 V DC

• Response Time: ≤ 8 ms (Status Input logic)

• Field Connection: Pressure Clamp Terminals (Direct wiring)

• Internal Current Consumption: 350 mA @ 5 V DC

Engineering Advantages

• Simplified Field Wiring: The integrated pressure clamp terminals facilitate direct wiring from field devices to the module. This eliminates the need for external terminal blocks, reducing cabinet clutter and decreasing the likelihood of wiring errors during commissioning.

• Versatile Signal Processing: The ADV157-S00 handles multiple signal types simultaneously. Engineers can configure channels for standard status monitoring or leverage the counting function for flow meters or encoder pulses, consolidating various I/O requirements into a single module slot.

• High-Density Isolation: 32-channel isolation prevents electrical surges from propagating through the backplane. This protects the system processor from field-side ground loops and transient spikes, a common issue in large-scale industrial plants.

• Optimized Power Efficiency: Consuming only 350 mA from the internal 5V supply, this module allows for higher I/O density within a single node unit without exceeding the power budget of the system bus.

FAQs

Is this ADV157-S00 unit brand new?

Yes. We supply this module as 100% Brand New original equipment. It ships in the original factory packaging to ensure performance integrity and compliance with your project's quality standards.

What is the primary difference between the ADV157 and the ADV151?

While both handle 32 channels, the ADV157 features integrated pressure clamp terminals for direct wiring and specific firmware logic for pushbutton edge detection and counting, whereas the ADV151 typically requires a separate terminal board connection.

Does this module require a separate power supply for the field side?

The field-side signals require an external 24 V DC power source to drive the inputs. The internal 5 V DC current draw listed in the specifications only powers the module’s logic and isolation circuitry.

How does the counting function operate?

The ADV157-S00 can track pulses from field contacts. Each channel assigned to the counting function increments the internal register on the leading edge of the 24 V DC signal, suitable for low-to-medium frequency pulse counting applications.
