1719 Ex I/O Installation Instructions
1719-A22, 1719-A24 Connections
S1 Switch Positions and X03 Terminal Assignment (1719-A22, 1719-A24)
The S1 switch and X03 terminal control the output deactivation of the I/O modules.
The output deactivation of the I/O modules only works for I/O modules that are equipped with a deactivation feature (1719-OB2, 1719-OB2L). I/O modules with and without a
deactivation feature can be installed on the same backplane; however, only the I/O modules that are equipped with a deactivation feature are controlled by the output
deactivation.
The backplanes are divided into five areas. Each area monitors different slots on the backplane. If I/O modules that are equipped with a deactivation feature are installed
on the backplane, the individual areas can be deactivated using an external switch.
Description Description

X7: Extension connection for 1719-A24
extension chassis.
Note: Online addition of an extension
backplane while the system is in Run mode is
not supported.
5 X02: 24V DC redundant power supply
6 X01: 24V DC power supply
ATTENTION: Damage to equipment
• Do not handle connections improperly as this can damage the backplane.
• Never supply a control voltage to X03.2…X03.6. On backplanes 1719-A22 and 1719-A24, output deactivation of the I/O modules can be controlled by a
voltage-free contact only.
• Only operate multiple adjacent backplanes using a common contact to avoid equalizing currents.
