3.7 Connecting up the RTU
Figure 3-1
For the power supply of the sensors, you can use the control outputs X10 or X11 of the RTU.
Connecting the digital outputs X30 ... X31
The outputs are designed as relays that switch through the signal of the relevant connector 0
/ 1 / 2 / 3 (reference potential) to the output 0L / 1L / 2L / 3L.
The terminals 0 / 1 / 2 / 3 can be supplied with voltage via the control outputs X10/X11 of the
RTU if this is configured. You specify the voltage value of control outputs X10/X11 in the
WBM ("Operating mode" > "Power supply") for the outputs X10, X11, X40 and X42 together.
You can connect two actuators to each of the two terminal blocks of the digital outputs. In
total, up to 4 actuators can be connected.
Assignment of the contacts based on the example of terminal block X30 for digital outputs 0
and 1:
● 0L / 0 Output 0
● 1L / 1 Output 1
Terminal block X31 is assigned accordingly, for digital outputs 2+3.

For the power supply of the connected actuators, you can use the control outputs X10 or
X11 of the RTU.
Connecting up the analog inputs X40 ... X43
You can connect up to 4 analog measuring transducers to the RTU.
The terminal blocks X40 and X42 each serve to control and supply 2 sensors. You specify
the voltage value (12 or 24 V) in the WBM ("Operating mode" > "Power supply").
The terminal blocks X41 and X43 are each used to connect the signal wires of two sensors.
