Dual-Rail Power Supply for CENTUM VP and ProSafe-RS Control Systems

The PW482-10 S2 serves as a dedicated power supply module within Yokogawa’s CENTUM VP and ProSafe-RS automation platforms. Engineers deploy this Style S2 unit to energize Field Control Units, FIO Node Units, and Optical ESB Bus Repeaters. Consequently, the module delivers stable dual-rail DC power for continuous process operation.

Technical Specifications

Dual Output Architecture

The PW482-10 S2 generates two independent DC rails from a single AC input source. The 5.1V DC rail powers processor logic and backplane circuits. Meanwhile, the 24V DC output supplies field transmitters and I/O signal conditioning. Therefore, engineers eliminate separate power supplies in compact control cabinets.

Redundancy and Reliability

Dual-redundant configurations allow two identical modules to share the load across slots P1 and P2. If one unit fails, the backup assumes full capacity without process interruption. This design suits critical applications in oil and gas, petrochemical, and power generation facilities.

Environmental Durability

The module operates reliably across a temperature range of -10°C to +55°C. Natural convection cooling eliminates moving parts and reduces maintenance requirements. Additionally, the compact form factor suits high-density rack installations in demanding industrial environments.
