Flex Analog/Digital Inputs
The RTCU LX5 eco has three flex analog inputs that can work in either analog or digital mode. The
configuration is conveniently done from the RTCU IDE I/O configuration dialog.
The operating range is from 0..30 VDC and the conversion resolution is 12 bit.
The input signal is connected between AINx and AGND. AGND must be connected to the
reference of the connected equipment. Please be aware that deviations may occur, as the system is
very noise-sensitive. Avoid long unshielded wires and significant fast-changing signals routed
parallel to the analog signals.
The inputs are low-pass filtered, ESD- and transient protected.
By default, the inputs are configured as voltage inputs. For replacement and configuration of the
hardware jumpers inside the device, please refer to the device configuration guide in Appendix C.
