TheYokogawa PW702-S1is an Input Power Supply Module specifically engineered for the CENTUM CS and CENTUM CS 3000 Distributed Control System (DCS) architectures. It converts 100-120 VAC utility power into the stable DC voltages required to operate the system's internal modules and backplane logic.

Features
N+1 Redundancy:Designed for mission-critical applications. When two PW702-S1 modules are installed in a redundant baseplate, they share the system load. If one unit fails, the remaining unit maintains full power without a system interruption or data loss.
Advanced Load Balancing:Features internal circuitry that ensures both modules in a redundant pair are utilized equally, extending the life of the internal components and capacitors.
Status Monitoring:Equipped with clear front-panel LED indicators:
READY (Green):Indicates normal operation and correct output voltage.
FAULT (Red):Indicates an internal error, over-voltage, or thermal shutdown.
Bumpless Failover:Integrated with the DCS diagnostic bus to provide "health status" to the operator console, allowing for proactive maintenance before a total rack failure.
Passive Cooling:Optimized for natural convection within industrial cabinets, reducing the risk of failure points associated with mechanical cooling fans.
