Connecting the power supply
The RHE46 Coriolis transmitter requires a regulated DC power supply of 12 to 24V
±10%. The power consumption is max. 4W.
1 Fuse (suitable for the cable being used, max. 10 A)
20 +24 V connection
21 Ground connection
22 Connection for protective conductor
1. →Connect the positive DC power connection of the power supply to the +24V
connection (20) and protect it with a fuse (1).
2. →Connect the negative DC power connection of the power supply to the
ground connection (21).
3. →Connect a protective conductor to a corresponding junction point and to the
connection for the protective conductor (22).
Connecting the RS485 interface
The RS485 interface is used for digital communications, for remote control
purposes, and to exchange data. It uses the Modbus protocol to establish a
permanent connection to a monitoring control system.
For the wiring of the RS485 interface, please refer to the wiring diagram (QR code
