Functions
Module supply
}
The module supply provides the module with voltage.
Signals at the output
}
"0" signal (0 V) at the output:
–
Output is high impedance
–
No current to the load
}
"1" signal (+24 V) at the output:
–
Output is low impedance
–
Current is supplied to the load
Periphery supply
}
The module routes the periphery supply from the module bus to the base module ter-
minals.
}
The periphery supply is used to supply the outputs.
Outputs
}
The head module sets the output status via the module bus.
}
The max. capacity at an output depends on the load (see characteristic). Connecting a
higher capacity may lead to an error.
}
Operation with electronic contactors has not been tested and may lead to errors.
Please contact our Customer Support team if you are using electronic contactors.
