Measuring output
Output signals A1 and A2
The output signals can be either load-independent DC
currents I
A
or DC voltages U
A
. The desired mode is set on DIP
switches and the setting range is programmed on a PC. A1
and A2 are not DC isolated and the same value is available
at both outputs.
Standard ranges for I

Output contact K
The output contact can be used:
a)
as an additional means of signalling operation of the
open-circuit sensor supervision when the transmitter
is used in conjunction with resistance thermometers,
thermo-couples, resistance sensors and potentiome-
ters.
b)
to monitor the measured variable in relation to a limit
or its rate-of-change where an additional means of
signalling operation of the open-circuit sensor super-
vision (see “a”) is considered unnecessary.
c)
to monitor the measured variable in relation to a limit
or its rate-of-change when measuring a DC voltage or
a current.
Note on a): The relay has to be activated by programming
its operating mode as “energised” or “de-
energised”.
Available operating modes are:
“Output at last value, relay energised”
“Output at last value, relay de-energised”
“Output at setting, relay energised”
“Output at setting, relay de-energised”
Relay pick-up/reset threshold:
1 to 15 kΩ, acc. to measuring mode and range
Note on b): The relay must be activated by programming:
“Output corr. to input variable, relay inactive”
The limit must also be programmed (see Section
“Limit”)
Note on c): It is only necessary to program the limit (see
remarks on “b)” above)
