Block diagram 24LI
The 24LI has 24 independent bi-directional inputs/outputs.
These lines are configured using the ICS software.
Input and output status is displayed for each line by an LED on the front plate.
The reference potential is earth or 0 V.
The output idle voltage of the lines corresponds to the system operating voltage,
i.e. type -48 V.
-24 V (optional) to a max. -60 V can be switched in.
An active line puts through 0 V as output or is 0 V as input.
The line current is a maximum of 150 mA. The line is switched off in the case of
excessive load.
