Product Overview

The YOKOGAWA SDV144-S33/PRP module functions as a specialized, high-density Digital Input Module, designed for reliable and high-availability signal acquisition in control systems. This essential YOKOGAWA component ensures rapid and dependable monitoring of on/off field statuses, such as switches and alarms.

The critical suffix /PRP indicates Peer-to-Peer Redundancy. This feature means the module is designed to work in a redundant pair with another identical module, ensuring maximum fault tolerance and continuous data acquisition from field devices. The module supports 24 V DC sinking or sourcing inputs, adhering to common industrial standards. The SDV144 base model indicates a high-density, typically 32-channel configuration.

Detailed Technical Specifications of the SDV144−S33/PRP

The YOKOGAWA SDV144-S33/PRP digital input module provides thirty-two (32) input channels in a compact form factor.

Redundancy and High-Density

The PRP feature is the core benefit, enabling the installation of two modules connected to the same field signals. If one module fails, the control system seamlessly switches to the redundant module, preventing any interruption in status monitoring. The high channel count (32 points) allows for efficient use of chassis space, maximizing I/O density for large systems. The module also incorporates input filtering, enhancing signal integrity by rejecting electrical noise and contact bounce.
