- Сollection and archiving data received from others devices via RS-485 interface (Modbus RTU or Modbus ASCII protocol).
- Measuring and archiving unified current (0..20 mA) or voltage (0..1 V or 0..10 V) signal.
- Remote display units BVI-TK-2 can be connected to channel which are not used in poll to display archived data.
- Archive is saved to SD-card.
- Archiving period is set programmatically.
- Personal settings for every channel to receive data from device or transferring data to BVI-TK-2.
- Nonvolatile real-time clock.
- DIN-rail mounting housing.
- LED indication of operating modes.
- Three archiving modes:
- static – data is written periodically over time from settings;
- dynamic – data is written if difference between current and previous value exceeds threshold value from settings;
- emergency – data is written if error occurs or on relay operation.
- Transferring and viewing archive on PC without SD-card ejecting can be done with special software (is supplied with device).
- Set up via RS-485 or SD-card.
