When installed in a redundant-capable backplane, the modules share the power load, ensuring that the system remains energized if an individual unit fails. Each module includes integrated overvoltage and overload protection circuits, providing a fault-tolerant environment for process control equipment. The 1 NC dry contact output allows for immediate alarm signaling to the controller in the event of an internal power fault, facilitating proactive maintenance.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How is the \"summable\" capacity of 20 A achieved when using two units?\u003c\/p\u003e\n\u003cp\u003eA: When two 140CPS11420 units are installed in a redundant-capable Quantum backplane, the backplane circuitry manages the parallel load sharing. The modules are physically and electrically synchronized to combine their current output, resulting in a total capacity of 20 A while maintaining voltage stability at 5.1 VDC.\u003c\/p\u003e\n\u003cp\u003eQ: What action should be taken if the \"Power OK\" LED turns off during operation?\u003c\/p\u003e\n\u003cp\u003eA: An off LED indicates either an input power loss or an internal module failure. Check the AC input voltage levels against the specified operating ranges (93–132 V or 170–276 V). If the input is within tolerance, check the status of the NC dry contact relay; if the contact is open (indicating a fault), the module must be replaced according to system safety protocols.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Ensure the module is fully inserted into the designated power supply slot on the Quantum backplane.
