4.6.3
Supply Voltage for DigOUTs
For optically isolated digital outputs, an external supply voltage must be applied. Basically, any power
supply may be used, provided it meets below stated minimal requirements.
4.6.4
Digital Outputs 1, 2 and 3
By default, the optically isolated digital outputs are defined as “General Purpose” and may be configured
via software.
