1)
Terminal 27 and 29 can also be programmed as input.
The digital output is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
Control Card, 24 V DC Output
Terminal number
12, 13
Output voltage
24 V +1, -3 V
Max. load
200 mA
The 24 V DC supply is galvanically isolated from the supply voltage (PELV), but has the same potential as the analog and digital
inputs and outputs.
