The Modicon 140-CPS-114-20 is a Summable Power supply, 115/230 Vac. 11 A module. It requires an input voltage of 93 - 138 Vac, or 170 - 264 Vac, and an input frequency of 47 - 63 Hz. Its input voltage total harmonic distortion should be less than 10% of the fundamental RMS value. There should be less than 1 second between input power interruptions during a half cycle at a full load and minimum rated line voltage / frequency. Its output to the Bus is 5.1 Vdc. It does have overcurrent and overvoltage protection. If the LED Pwr ok is on and green, then power is currently being supplied to the Bus. On terminals 1 and 2 of the module’s power strip, a normally closed relay contact at 22 Vac, 6A / 30 Vdc is available. These contacts may be used to signal input power OFF. the relay will also de-energize when input power drops below 8 Vdc. The 140CPS11420’s internal power dissipation is less than 12 W at full load. It is also compatible with the 140CPS11410 which is an older AC module.
If you are using NxT, the ProWORX NxT power calculation is incorrect for the 11 amp output for the Schneider Electric 140-CPS-114-20 module. Users should ignore the power calculation bar, and perform the calculation manually. The power calculation will be corrected in ProWORX NxT version 2.2 and ProWORX 32. If you are using Concept, version 2.5 SR2 and earlier do not recognize the health bit. Upgrade your software version to resolve this issue. Use only compatible combinations of power supplies in the Quantum backplane as stated above. Remove the power line prior to insertion or removal of the module. If these precautions are not take, serious injury and equipment damage could occur.
