Multifunctional device depRTU-3M

The multifunctional device depRTU-3M is designed to measure the AC current strength and control the presence of voltage in the main current-carrying circuits of the electrical device for the purpose of integrated monitoring and control of cells of electrical substations of different voltage classes as part of the ACS and TM systems. The device is placed directly in the switchgear and control centre of electrical installations. The device contains: - 3 channels of pulse discrete output for control of the cell switch; - 7 channels of discrete input, not requiring external power supply, for connection of limit switches of "dry contact" type; - a channel of discrete input "EN" - for prohibition/permission of control functions of the module; - 3 channels of measurement and control of voltage presence in the main current-carrying circuits of the electrical apparatus. Voltages are supplied from the middle points of capacitive dividers; - 2 channels for measuring the AC power; - 2 input channels for DC power supply.
