5.4.1 Connecting the power supply for the RFH620
The RFH620 requires a supply voltage of 10 ... 30 V DC (functional extra-low voltage
in accordance with IEC 364-4-41 (VDE 0100 (Part 410)) for operation. The functional
extra-low voltage can be created using a safety transformer in accordance with IEC 742
(VDE 0551). The maximum current consumption is 4.5 W.
The RFH620 is supplied with 10 ... 30V DC via connection module CDB620 or
CDM420, in case of installing an additional field bus gateway CMF400 or display
CMD400 into CDM420 with 18 ... 30 V DC.
Connecting supply voltage
When wiring the RFH620 using connection module CDB620 or CDM420, the RFH620
data and function interfaces are contacted to the connection module together with the
power supply.
1. Ensure that the connection module's supply voltage has been switched off.
2. Ethernet version: Connect the RFH620 12-pole plug via a corresponding cable (e.g.
2042916) to the connection module's 15-pole socket and screw it tight
- or –
use the external power supply.
5.4.2 Wiring serial data interface
The maximum data transfer rate depends on the cable length and the interface type.
