4.4.10 Energy-storing signal communication module NWDF1-S1
 Energy-storing signal communication module components can obtain
the "Energy storage" or "Energy release" status information of the electric operating
mechanism of the circuit breaker via the upper computer.
Outline and installation dimensions are the same with the outline and installation
dimension diagram of the remote intelligent I/O module.
4.4.11 Voltage conversion module NWDF1-P2
 As the maximum rated input of the frame controller is AC500V in case of voltage detection, a
voltage conversion module is required to reduce the voltage below AC500V when the input is
greater than AC400V.
