8.1 Inputs
All ten inputs can be used as digital inputs but only some (IN1, IN2, IN3, IN4, IN5, IN6 and IN7 on EV3 MVC; IN1, IN2, IN3, IN4, IN5,
IN9 and IN10 on EVD MVC) can be configured as analogue.
Inputs IN1 and IN2 can be configured using parameters I23, I24 (controller), I26 and I27 (expansion), as shown in the table below,
whereas the other analogue inputs are of the temperature type.
Type AI universal
Parameter value
I23 - I24 - I26 - I27
Description
0 NTC / Digital input
1 4-20 mA
2 0-10 V
Important: in EV3 MVC, if one of the inputs IN1/IN2 has been set to power, the other one must also be. If this does not happen the
reading of the input set to power will be affected by the offset.
The type of probe chosen affects the unit in which measurements are taken: probes measuring temperature are in °C or °F according
to the parameter C59 setting, while probes measuring power or voltage use the units Pa or % (%rh in EVJ LCD) according to the
conversion scales set by parameters I29-I32 that determine the values at both ends of the scale for sensors configured as humidity,
CO
