Electrical connection
• Observe the cable specifications.
• Observe the ‘Interface plan’ in the drawings set.
• When routing the electrical lines, follow all applicable national
safety regulations for the installation and operation of
electrical devices.

installations on board of ships and observe the local
conditions.
• Connect the input wiring of the heated sample components
(temperature-resistant as needed).
Digital communication
Modbus® communication
Transmission of measured values and status signals as well
as analog input, digital input and digital output signals to
host systems, e.g. standard Windows applications via M-DDE
server.
Modbus slave protocol in the RTU (Remote Terminal Unit)
mode via the RS485 interface.
