7.3.16 Control management
Each GPO can sink a current of up to 300mA maximum in the closed state and can accept up to 48V in the
opened state. The courant leakage is less than 1µA when opened and the resistance is less than 2 ohms when
closed. The GPO can be reset to its default values.
GPI:
The optically isolated GPI allows the user to drive the device externally.
There are two pins: one positive and one negative. The way to trigger it is to provide a current (10mA/3V min
and 45mA/24V max). The GPI is protected over polarity inversion.
There are two activation polarities: the input can be active when powered or when unpowered.
The mode can be :
- FREE: manual, not linked to an action, driven by automation
- TAKE: when input is active, a TAKE is generated on one or several screens.
The GPI can be reset to its default values.
