The RIO EC X2 bus coupler connects the XRIO interface on Schleicher XCx
500/540 to modules in the RIO I/O series. The XCx bus coupler has the
same technical features as the economy bus couplers in the EC series.
A bus station comprises the bus coupler and up to 8 RIO I/O expansion
modules with 128 digital or 56 analog channels. The I/O modules are
connected on the DIN rail on the coupler. The internal bus is created by slide
contacts.
For further information on XCx controllers please refer to the system
descriptions and operating manuals (→ page 67).
