CURRENT-VOLTAGE CONVERTING MODULE USED IN NUCLEAR PLANT SAFETY SYSTEM

摘要

A current-voltage converting module for a control system of a nuclear power plant is provided to reduce the number of subracks and cabinets at the nuclear power plant by the design according to the 3U size of a VME(Versa Module Eurocard) bus regulation through a plurality of channels. A current-voltage converting module for a control system of a nuclear power plant includes a connector, a first channel converting unit, a second channel converting unit, and a DC/DC converting unit. The connector receives the operating power from the outside, and inputs and outputs an input signal and an output signal separately. The first channel converting unit converts the first input signal which is received from the connector to a first voltage signal to output the first voltage signal to the connector. The second channel converting unit converts the second input signal which is received from the connector to a second voltage signal to output the second voltage signal to the connector. The DC/DC converting unit converts the operating power which is received from the connector to the powers with different intensity to supply the powers to the first and second channel converting units.
