Serial Interfaces
Transfers measured values and status signals to host systems, e.g. to standard Windows
applications via Modbus DDE Server. Modbus slave protocol in RTU (remote terminal unit)
mode. Either the RS232 or the RS485 interface can be used (configurable). Interface
galvanically isolated from ground.
Digital Outputs
Floating double throw contacts, max. contact load rating 30 VDC / 1 A. Relays are shown in
the unpowered state. The unpowered state is the failure mode ("fail safe").
Analog Outputs
4–20 mA, common negative pole, galvanically isolated from ground, freely connectable to
ground, max. gain relative to protective ground potential 25 V, max. working resistance
750 Ω. The output signal cannot be lower than 0 mA.
Power Supply (see page 20)
85–250 VAC, 48–63 Hz, max. 6 A breaker
At the factory two jumpers are inserted in the analog output terminals 31–32 and
33–34. If no signal leads are installed, these jumpers close the output current
circuits and prevent the display of status message 30 "Broken analog output line"
(see page 47).
The respective jumper must be removed prior to connecting the electrical lines to
the analog output terminals.
