over the same two-wire cable. This mode is provided for connec-
tion of measuring transducers without separate power supply
(sensors in two-wire version).
•
In passive mode the sensors are not powered, only the measured
value is transmitted. This input is for connection of transmitters
with their own separate voltage supply (sensors in four-wire ver-
sion). The VEGAMET 841 can also be looped into the existing
circuit like a normal ammeter.
Note:
With a VEGAMET 841 in Ex version, the passive input is not available.
5.3 Connecting
The voltage supply and inputs and outputs are connected via the
spring-loaded terminals.
