Product Overview

The YOKOGAWA SDV531-L33/PRP module functions as a critical, high-availability Digital Output Module, designed for non-stop control applications in demanding industrial environments. This essential YOKOGAWA component switches external field devices on or off, translating control logic into physical action.

The key feature is the suffix /PRP, which indicates Peer-to-Peer Redundancy. This design allows the module to be installed and synchronized with an identical module, ensuring non-stop operation and eliminating the output path as a single point of failure.

The SDV531 base model typically indicates a 16-channel digital output module. The module provides 24 V DC sourcing outputs, the standard voltage for industrial control circuits.

Detailed Technical Specifications of the SDV531−L33/PRP

The YOKOGAWA SDV531-L33/PRP digital output module provides sixteen (16) output channels with full support for redundant configurations.

Redundancy and Reliability

The PRP functionality ensures that two SDV531−L33/PRP modules can be configured to share the same output field wiring via a specialized terminal block or connection. If one module fails, the control signals are instantly handled by the redundant partner, ensuring uninterrupted control over the field devices. The module's internal design prioritizes high reliability, making it ideal for critical applications where downtime is unacceptable.

Frequently Asked Questions (FAQ)

Q1: What is the main benefit of the /PRP feature on the SDV531−L33/PRP module?

A1: The main benefit is the ability to achieve non-stop, fault-tolerant digital control via Peer-to-Peer Redundancy, ensuring zero interruption of output signals upon a single module failure.

Q2: How many output channels does the SDV531−L33/PRP module provide?

A2: The YOKOGAWA SDV531-L33/PRP module provides 16 digital output channels.

Q3: Is the SDV531−L33/PRP module used in safety systems (SIS)?

A3: While it provides high availability, the SDV531−L33/PRP is typically used in basic process control systems (BPCS) for critical control. Dedicated safety modules (like the SAI or SDI series) are usually used for certified SIS functions.

Q4: What is your policy if the module has a quality issue upon arrival?

A4: We support a 30-day return window if there are any quality issues with the YOKOGAWA SDV531-L33/PRP module.
