Rs20/Rs30/Rs40: Supply Voltage And Signal Contact - Hirschmann RS20 Series User Manual

Before starting operation of the device, check whether the default settings
of the DIP switch correspond to your requirements.
2.1.5 RS20/RS30/RS40: supply voltage and
signal contact
The supply voltage and the signal contact are connected via a 6-pin terminal
block with a snap lock.
Caution!
Note the safety instructions
only connect a supply voltage that corresponds to the type plate of
your device. Make sure that the contact load capability of the signal
contact is not exceeded
Supply voltage for RS20/RS30/RS40
The supply voltage can be connected redundantly. Both inputs are uncou-
pled. There is no distributed load. With redundant supply, the power sup-
ply unit supplies the Switch alone with the higher output voltage. The
supply voltage is electrically isolated from the housing.
See "Insulation voltage" in chapter
You can choose between DC or AC voltage when connecting the supply
voltage. You use the +24V and 0V pins to connect the AC voltage

1 – DC voltage, voltage range: 9.6 V DC to 60 V DC
2 – AC voltage, voltage range: 18 V AC to 30 V AC
Note: With non-redundant supply of the main voltage, the device reports
a loss of power. You can avert this message by applying the supply volt-
age via both inputs, or by changing the configuration in the Management.
