Key Features and Benefits

• High Availability Design: The 8A output supports redundant setups where multiple power supplies share the load, eliminating single points of failure.
• Extended Ride-Through: A 13ms hold-up time at 48V maintains output during short input dips, preventing nuisance system shutdowns.
• Comprehensive Electrical Protection: Integrated overvoltage and overload circuits protect the supply and the valuable modules on the backplane.
• Integrated System Monitoring: The NC alarm contact provides a remote signal for SCADA or control system integration, alerting operators to a supply fault.
• Clear Operational Feedback: The front-panel green PWR OK LED allows for instant visual verification of module health.
• Robust Industrial Design: Built to meet CE standards for safety and EMC, ensuring reliable operation in industrial environments.

Installation and Application Notes

• For redundant operation, install multiple 140CPS42400C modules in parallel as per Quantum system design guidelines.
• Protect the input circuit with the specified 2A time-lag fuse to safeguard against short-circuit conditions.
• Ensure the input DC source is within the 48-60VDC range and capable of supplying the necessary current (≤3.8A per module).
• Wire the alarm output (NC contact) to your plant alarm system or PLC digital input for remote fault notification.
• Account for the module's power dissipation (17.2W) in your cabinet thermal management design.
• Use the PWR OK LED for quick troubleshooting during commissioning and routine maintenance checks.

Frequently Asked Questions (FAQ)

• What is the difference between "summable" and "redundant" output?
  "Redundant" (like this 140CPS42400C) means modules are designed to be paralleled for load-sharing and fault tolerance. "Summable" typically refers to adding current capacity, which this module also supports in a redundant architecture.
• Why is a 13ms hold-up time important?
  It allows the PLC system to ride through very brief power interruptions or brownouts without shutting down, greatly improving operational continuity.
• How do I use the alarm output contact?
  The Normally Closed (NC) contact opens if the power supply fails. Wire it in series with an external indicator or a PLC input to trigger an alarm.
• Can this module be used as a single, non-redundant power supply?
  Yes, the 140CPS42400C can operate standalone to provide 8A of 5.1VDC power to a Quantum backplane.
• What happens during an overload?
  The internal overload protection will limit or shut down the output to protect the module, and the alarm contact will likely change state.
• Is the input fuse user-replaceable?
  Specifications indicate a required 2A time-lag fuse on the input line; this is typically an external fuse installed in the panel, which is user-serviceable.
