Introduction
Current outputs
The floating current outputs (0) 4 ... 20 mA
are used for transmitting measured values.
An output filter can be programmed, the
fault current value can be specified.
See page 76.
Relay contacts
2 relay contacts for limit values. Adjustable
for the selected process variable:
hysteresis, switching behavior (MIN/MAX
limit), contact type (N/O, N/C) and delay
(page 98).
Wash (cleaning function)
This contact can be used for controlling a
rinsing probe or for indicating the active
parameter set (page 112).
Signal outputs
The device provides two current outputs (for transmission of
measured value and temperature, for example).
Relay contacts
Four floating relay contacts are available.

Alarm
An alarm can be generated by Sensocheck,
flow monitoring or current failure
(page 94).
PID controller
Configurable as pulse length or pulse frequency controller (page 105).
