5.9 Analog outputs
Analog outputs are available for devices with corresponding I/O extensions only. See nameplate. Analog
outputs may be remote controlled.
Connection to an analog input card of a PLC or a control system
The device is an isolated measurement device. The module outputs are galvanically connected, but the
modules isolated from each other. To reduce the influence of disturbances shielded a twisted-pair cables
should be used. The shield should be connected to earth on both opposite ends. If there are potential
differences between the ends of the cable the shield should be earthed on one side only to prevent from
equalizing currents.
Under all circumstances consider as well appropriate remarks in the instruction manual of the system to
connect.

5.10 Modbus interface RS485
Via the optional Modbus interface measurement data may be provided for a superior system. However,
the Modbus interface cannot be used for device parameterization.
1) One ground connection only.
This is possibly made within the
master (PC).
