Extension bus
Up to three extension modules can be freely connected at the left of the control.
The extension modules have to be attached without any gaps via the extension
bus base modules on the left side of the IndraControl XM21, XM22 and supplied
with the same 24 V supply voltage. Switch on and off the 24 V supply voltage of
the extension modules synchronously with the IndraControl XM21, XM22. For
the extension modules, refer to: R911345570

S20 interface
Up to 63 S20 modules can be connected to the S20 interface on the right of the
IndraControl XM21, XM22 via S20 bus base modules. The number of connecta-
ble modules depends on the total current consumption of the S20 modules. The
IndraControl XM21, XM22 can provide up to 2 A for the power supply of the S20
modules.
