Smart Transmitters
Configuration
For smart transmitters the Commulog is
simply connected into the 4...20 mA
analogue circuit.
•
A minimum load of 150
Ω
must always
be present on the line.
•
The maximum load is 650
Ω
.
For the Deltabar differential pressure
transmitter:
•
There is no need to pressurize during
configuration.
•
4
…
20 mA signals can be simulated
for the adjustment of instrumentation.
•
The differential pressure can be read
from matrix field V0H0 (Display 00).
Field Use
The Commulog VU 260 Z can also be
connected directly to the smart
transmitter:
•
A rugged, splash-proof housing
means it can be used outdoors.
•
It is suitable for use in explosion
hazardous areas Zone 1.
