Introduction
Current outputs
The floating current outputs (0) 4 ... 20 mA
are used for transmitting measured values.
The output curve can be linear, bilinear or
logarithmic. An output filter can be pro-
grammed, the fault current value can be
specified. See page 62 onwards.
Relay contacts
2 relay contacts for limit values. Adjustable
for the selected process variable: hysteresis,
switching behavior (MIN/MAX limit), con-
tact type (N/O, N/C) and delay (page 84).
Wash (cleaning function)
This contact can be used for controlling a
rinsing probe or for indicating the active
parameter set (page 98).
Signal outputs
The device provides two current outputs (for transmission of
measured value and temperature, for example). The output curve is
adjustable (linear, bilinear or logarithmic), see page 62 onwards.
Relay contacts
Four floating relay contacts are available.

Alarm
An alarm can be generated by Sensocheck,
flow monitoring or current failure
(page 80).
PID controller
Configurable as pulse length or pulse frequency controller (page 94).
