4. Brief description

Resistance thermometers, thermo-couples, resistance
sensors, potentiometers or DC current or voltage sources
are connected to the programmable transmitter EURAX
V 604 which then converts the corresponding input signals
into impressed current or voltage output signals.

Explosion-proof "Intrinsically safe" [EEx ia] IIC versions
approved for processing measured variables in explosion
hazard zones rounds off this series of transmitters.
Measured variables and measuring ranges are programmed
with the aid of a PC, a programming cable and the pro-
gramming software. Specific measured variable data such
as output signal, transmission characteristics, active direction
and open-circuit sensor supervision data can also be pro-
grammed.
Devices supplied ex stock are programmed as follows:
– Measuring input
– Measuring output
– Settling time
– Break monitoring
– Mains ripple suppression
– Limit function
