Product Description
The SAT145-S63/PRP S2 is a high-density analog input module designed for the Yokogawa CENTUM VP Distributed Control System (DCS). It provides 16 isolated input channels optimized for thermocouple and low-level millivolt (mV) signals, making it an essential component for high-precision temperature monitoring and process control.
This module supports a wide range of thermocouple types and mV inputs, enabling accurate acquisition of temperature measurements in complex industrial environments. With high-speed data processing and advanced isolation protection, the SAT145-S63/PRP S2 ensures stable and reliable signal conditioning for critical process instrumentation.
The PRP (Parallel Redundancy Protocol) enhancement allows the module to operate within redundant dual-network architectures, ensuring continuous communication and eliminating single points of failure. Designed for harsh industrial environments, the hardware is ISA S71.04 G3 compliant, providing resistance to corrosive atmospheric contaminants and maintaining stable operation across a wide temperature range of −20°C to 70°C.

-
Extended operating temperature range suitable for extreme environments
-
PRP network support for dual redundant communication paths
-
Improved compatibility with high-availability CENTUM VP architectures
While both modules support 16 thermocouple/mV channels, the S63 version is typically selected for installations requiring enhanced environmental resilience and advanced network redundancy.
Application Scenarios
The SAT145-S63/PRP S2 is widely used in industries requiring precise temperature measurement and high system availability, including:
-
Petrochemical and chemical processing plants
-
Power generation facilities
-
Oil and gas production systems
-
Refining and heavy industrial process units
Typical monitoring applications include reactor temperature measurement, furnace monitoring, heat exchanger control, and turbine temperature supervision.
Engineering FAQ
Does this module require a specific terminal block for thermocouple inputs?
Yes. To utilize internal Reference Junction Compensation (RJC), the module should be paired with a compatible pressure clamp terminal block that includes an integrated temperature sensor.
Is the module hot-swappable?
In a redundant CENTUM VP system configuration, the SAT145-S63/PRP S2 can be replaced while the system remains online. However, proper maintenance procedures and safety guidelines should always be followed to avoid process disturbances.
