DC ammeters and voltmeters Щ120П are installed on the rectifier door and provide measurement and conversion of current and voltage in DC circuits into unified output DC signals and serial digital interface RS485
RS485 interface — additional option of the tool
Features and benefits:
1) Convenient reprogramming using built-in buttons or via RS485 interface:
- Range of indications, decimal point position;
- Level of monitored values of input signals (settings);
- Changes in the brightness of digital indicators;
- Interface parameters.
2) The communication interface RS485 allows transferring information to the upper level system, as well as combining digital tools into a single network;
3) The availability of analog and discrete outputs allows the tool to be integrated into the existing telemechanics system;
