6.6 Signal Interface Connection
6.6.1 X1 AD Converter
The X1 analog inputs can be used for voltage measurement, as well as e.g. for a joystick
as AD converter.
The 5 V
DC
±3 % / max. 100 mA voltage is supplied by the MCC-2.
Input voltage: 0 to 5 V
Resolution: 10 Bit
A/D conversion time: about 15 µs
Input resistance: 47 k
Ω
The input A/D ENABLE is a digital input (max. 5 V), which can be used e.g. as joystick
Enable. This input is only analyzed by software (see MiniLog-Comm).
Specific information for processing the input signals you’ll find in the programming manual
MiniLog-Comm.

CAUTION
Danger of device damage!
Do not exchange X1 and X2!
To improve the accuracy of measurement of the AD converter, use a shielded cable.
We recommend using the shielding as GND analog. With PELV Grounding (except for
SELV supply, see chap. 3) this can be additionally wired to PE. Make sure that no
reverse current couple into the GND Analog shielding. GND Analog should not be
connected to PE, if there is SELV supply.
