Digital inputs
Please refer to the ScriptEasy manual for more information on I/O management.
16 digital inputs can work in 2 different modes depending on jumper configuration:
◼
Schematic diagram:
➢
‘Internal power supply’ mode
(default mode):
With this mode, all common pins are internally linked to the ground.
When a digital input is connected with the common, this input’s value switches to ‘1’; otherwise it stays on ‘0’.
➢
‘External power supply’ mode:
With this mode, all ‘common’ pins are linked together but they are no longer connected to the ground. Now, an
external power supply is necessary.
An external power supply between 5 and 25 V is applied to the common. If a digital input is connected to the
ground, this input’s value switches to ‘1’; otherwise it stays on ‘0’.
