RS20/RS30/RS40: supply voltage and
signal contact
The supply voltage and the signal contact are connected via a 6-pin terminal
block with snap lock.
Supply voltage for RS20/RS30/RS40
The supply voltage can be connected redundantly. Both inputs are
uncoupled. There is no distributed load. With redundant supply, the power
supply unit with the higher output voltage supplies the device on its own.
The supply voltage is electrically isolated from the housing.
See “Insulation voltage” in section
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
(see
figure 20)
.
Figure 20: Connecting the supply voltage to the 6-pin terminal block
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
With a non-redundant supply of the supply voltage, the device reports the
loss of a supply voltage. You can prevent this message by changing the
configuration in the Management.
Signal contact for RS20/RS30/RS40
The signal contact (“FAULT“, pin assignment of terminal block
see
figure 20
) is used to monitor the device function, and thus
supports remote diagnostics. You can specify the type of function
monitoring in the management.
You can also use the switch Web page to switch the signal contact
manually and thus control external devices.
The potential-free signal contact (relay contact, closed circuit) reports
through a break in contact:
The detected inoperability of at least one of the two voltage supplies
(voltage supply 1 or 2 is below the threshold value).
The device is not operational.
