The Modicon 140CPS12420 is a 115/230V AC Standalone/Redundant 11A Power Supply Module in the Quantum Series. The module is able to fully operate in two modes: Standalone and Redundant. It has an internal power dissapation of 11W. The 140CPS12420 is not designed to require a external EMI filter, ferrite bead, or Olflex cable.
The following is the 140CPS12420 Wiring Diagam
A normally closed relay contact rated at 220V AC, 6A / 30V DC, 5A is available on terminals 1 and 2 on the power terminal strip. This contact set may be used to signal input power OFF. The relay de-energizes when input power drops below 70V AC when input voltage is set to 115V AC, or 140V AC when the input voltage is set to 230V AC. When voltage is on the module is set to 115V, the input voltage should only range between 93 to 138V AC. When voltage is set to 230V, the input voltage should range frm 10 to 263V AC. The 140CPS12420's input frequency is 47 to 63 Hz. The module does containg over-current and over-voltage protection. External fusing should use a 2.0A slow-blow.
