• Do not exceed the maximum simultaneous load on outputs Y1 ... Y4 (see
"Engineering")!
• A power amplifier may be used to connect additional valve actuators to Y3 and Y4
(see Desigo RXC installation guide, CA110334).
• For information on actuators compatible with the RXC32 controller, refer to the
relevant application descriptions (see Desigo RXC applications library, CA2A3810)
• The voltage for devices with an AC 24 V supply (G) can be derived either from the
controller or from an external source (see the Desigo RXC installation guide
CA110334).
If the connected devices receive their supply from the controller the power
consumption of these devices must be taken into account when sizing the
transformer.
