Isolated analogue converter UC-025P

Analog converter UC-025P

UC-025P is one-way galvanically isolated converter. It is intend for use in industrial applications, where different interfaces must be used and isolation is needed. This device has voltage input, current input and RS-232/RS-485 serial interface. Output can be voltage or current, in certain limits of course. It is microcontroller based, which gives the user flexibility to make corrections and offset of the output signal, compared to the input. This converter has the unique function to convert RS-232 based data to analogue output signal. For now the output DAC is 10 bits, but in the future we plan to expand it to 12 bits. Mounted on a standard М36 DIN-bus.

Operation mode of UC-025P

UC-025P starts to work immediately after power supply connected. Depending on selected input signal two choices are possible - data reading from RS-232 input or analogue signal measurement (voltage or current). Then read/measured data is processed, converted and transferred to the analogue output (voltage or current). This converter can have different kind of input and output, which is determined by the four DIP-switches on the main board.
