Two signal outputs programmable for measured values (freely
scalable, linear, bilinear, log) or as continuous control output (control
parameters programmable).
Current loop:
Maximal burden:
Two potential-free contacts programmable as limit switches for
measured values, controllers or timer with automatic hold function.
Maximum load: 100 mA/50 V
Two potential-free contacts (one normally open and one normally
closed). Summary alarm indication for programmable alarm values
and instrument faults.
 Normally open contact: closed during normal operation, open on
error and power loss.
 Normally closed contact: open during normal operation, closed on
error and power loss
Maximum load: 100 mA / 50 V
One input for potential-free contact to freeze the measuring value or
to interrupt control in automated installations (hold function or remote
off).
 RS485 interface (galvanically separated) for communication via
Modbus or Profibus DP
 USB interface for logger download
 HART interface
 RS232 interface for logger download with HyperTerminal
No data loss after power failure. All data is saved in non-volatile
memory. Overvoltage protection of inputs and outputs. Galvanic sep-
aration of measuring inputs from signal outputs.
