3.3.4 Digital Input / Output
DSUB-9 Female connector for digital input and output
The digital input is isolated and can measure up to +50 VDC with programmable Schmitt trigger
levels. Digital output is also isolated using a PhotoMOS relay.
3.3.5 Communication Ports
DSUB-9 Male connector for CAN 2.0B and RS-485 communication
This interfaces can be used for additional sensor connection (pyranometer, weather,
temperature etc.). All data are fully synchronized to the analoge input data (voltage, current,
additional AI). It 12VDC for power supply (if needed).
