The Yokogawa PW302-S4, also cataloged as the PW302 Power Supply Module, operates as a dedicated hardware component for regulated DC power distribution within CENTUM CS3000 and VP control stations.
The PW302 series distinguishes variants based on input voltage compatibility. Select the appropriate configuration to ensure adherence to site AC distribution standards.

The module executes power regulation through internal conversion stages, providing channel-to-channel isolation to prevent electrical noise coupling between the logic-level DC rails and auxiliary I/O loops. It supports dual-redundant power architectures where two units operate in parallel with automatic load sharing. Integrated protection circuits monitor for thermal overloads, overvoltage, and overcurrent conditions, triggering an automatic shutdown if output parameters deviate from defined tolerances. Furthermore, the module ensures cold junction compensation (CJC) stability for precision analog input modules by maintaining consistent reference voltage levels across the backplane bus.
Q: Does the PW302 support hot-swap replacement?
A: Yes, the module supports hot-swap functionality within redundant configurations. Ensure the control station backplane provides sufficient mechanical support and electrical interlocking to prevent short-circuits during module insertion or extraction while the system remains energized.
Q: What is the primary indicator of a redundancy failure?
A: The front-panel LED array includes dedicated indicators for redundancy status. A change in state from steady green to a flashing or extinguished condition identifies a loss of handshake or synchronization between paired power modules.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
Finding brand new, original modules is critical for our safety. This team delivers factory-fresh components with full certification. Their commitment to only selling new products makes them our most trusted partner.
We have sourced Honeywell and Schneider parts here for two years. Every shipment arrives well-packaged with original factory seals intact. Clear communication and the best lead times in the industry.
