YOKOGAWA PSCAMAAN Power module
The Yokogawa PSCAMAAN is a specialized power supply module, typically utilized within the CENTUM VP or CENTUM XL Distributed Control System (DCS) architectures.
It is designed to provide stable, reliable power to system nests and field control units, ensuring the continuous operation of critical industrial processes.
1. Introduction
The PSCAMAAN serves as a Power Supply Module that converts standard input voltages into the regulated DC power required by Yokogawa’s control hardware.
In the world of industrial automation, power reliability is non-negotiable;
the PSCAMAAN is engineered with high-grade components to prevent system downtime caused by electrical fluctuations or failures.

4. Product Advantages and Features
High Reliability: Built for 24/7 continuous operation in harsh industrial environments (high heat, humidity).
Redundancy Support: Can be installed in a dual-redundant configuration; if one module fails, the second takes over seamlessly without interrupting the process.
Hot-Swappable: In many configurations, these modules can be replaced while the system is live, minimizing maintenance downtime.
Strict Regulation: Provides “clean” power with low ripple noise, protecting sensitive CPU and I/O cards from electrical interference.
