Redundancy

For highly reliable transmissions, two redundant transmission lines can be config-
ured and the isolated voltage outputs of the two devices at the end of the line can
be connected in parallel to the input of the device to be synchronized. If input
signal monitoring is activated, the voltage outputs will be disabled when an alarm
occurs. This setting must be assigned for low-active output signals. For a
high-active output signal, monitoring of the output circuit can be activated at the
120 VDC voltage output
