OPEARTING MANUAL
5.2
Digital Interfaces
The DM sensors can be optionally equipped with an USB-, RS232-, RS485-, Profibus DP-*, Modbus
RTU-* or Ethernet-interface. If you want to install an interface, plug the interface board into the place
provided, which is located beside the display. In the correct position the holes of the interface match
with the thread holes of the electronic box. Now press the board down to connect it and use both
M3x5 screws for fixing it. Plug the preassembled interface cable with the terminal block into the male
connector of the interface board.
* Not available for 4M
The Ethernet interface requires at minimum 12 V supply voltage.
Please pay attention to the notes on the according interface manuals.
5.3
Relay Outputs
The DM can be optionally equipped with a relay output PCB. The relay board will be installed the same way as the digital interfaces. A
simultaneous installation of a digital interface and the relay outputs is not possible. The relay board provides two fully isolated switches,
which have the capability to switch max. 60 VDC/ 42 VACRMS, 0,4 A DC/AC. A red LED shows the closed switch.
