Key Features and Benefits

• Wide Input Voltage Range: Operates reliably from 48 to 60VDC, accommodating common industrial DC power sources.
• Summable Output Current: The 8A output can be combined with other 140CPS41400C modules to meet higher backplane power demands.
• Comprehensive Protection: Internal overvoltage and overload safeguards protect both the supply and the connected Quantum modules.
• System Reliability: The 13ms hold-up time at 48V bridges brief input interruptions, preventing system resets.
• Integrated Alarm Signaling: The NC alarm contact provides a dry signal for remote monitoring of power supply status.
• Clear Local Indication: The green PWR OK LED offers immediate visual confirmation of proper operation.

Installation and Application Notes

• Ensure the input DC source (48-60VDC) is stable and can deliver up to 3.8A input current.
• Install the specified 2A time-lag fuse on the input line for branch circuit protection.
• For systems requiring more than 8A, multiple 140CPS41400C modules can be configured in parallel for summable current output.
• Connect the alarm output (NC contact) to your control system for remote fault monitoring and alerting.
• Mount the module in a well-ventilated area within the Quantum rack, respecting standard module spacing.
• Use the green PWR OK LED for quick visual diagnostics during startup and maintenance.

Frequently Asked Questions (FAQ)

• What is the primary purpose of this module?
  The 140CPS41400C provides clean, regulated 5.1VDC power to the backplane of a Modicon Quantum PLC rack for CPU and I/O module operation.
• What does "summable output" mean?
  It means you can install multiple 140CPS41400C power supplies in the same system. Their output currents add together to support racks with higher power requirements.
• What protections does it have?
  The module features internal overvoltage protection (OVP) and overload protection (OLP) to ensure safe operation.
• How is a power failure indicated?
  Locally by the green LED turning off. Remotely via the alarm module's Normally Closed (NC) contact, which will change state.
• What is the hold-up time, and why is it important?
  The 13ms hold-up time is the duration the output remains within specification after input power fails. It helps prevent the PLC from restarting during very brief power glitches.
• Can I use this with a 24VDC source?
  No. The 140CPS41400C requires an input voltage between 48 and 60 Volts DC for proper operation.
