12. OPTIONAL INPUT / OUTPUT CONFIGURATION
12.1. Digital input module
Please refer to the ScriptEasy manual for more information on I/O management.
This module provides 16 digital inputs and 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’.
Select internal or external power supply mode:
