Product Description

The A2SDV505-S000 (A2SDV505) is a high-precision signal conditioning adaptor designed for Yokogawa ProSafe-RS and CENTUM VP I/O subsystems. It converts low-level field signals—including millivolt (mV), thermocouple (TC), and Resistance Temperature Detector (RTD) inputs—into standardized digital data for the control system.

Engineered for high-integrity process environments, the A2SDV505 provides galvanic isolation and signal linearization to ensure accurate measurements even in electrically noisy industrial settings. Its modular, plug-on design allows quick installation on compatible baseplates, supporting both safety-instrumented and standard process control applications.

Technical Specifications

Application

• Integration of diverse sensor types (TCs, RTDs, mV signals) into safety or standard process loops

• High-integrity process control environments requiring noise-resistant measurement

• Signal conditioning and linearization for ProSafe-RS and CENTUM VP systems

Frequently Asked Questions

In what scenarios is the A2SDV505-S000 typically used?
It is primarily used in heat-intensive processes where multiple sensor types must be monitored simultaneously, such as furnace temperature control, distillation columns, and reactor thermal profiling.

Does this adaptor handle cold-junction compensation (CJC) for thermocouples?
Yes, the A2SDV505 includes built-in CJC circuitry when used with compatible terminal blocks, ensuring accurate thermocouple measurements regardless of ambient terminal temperature.
