Analogue output module
 passive outputs
 External power supply: 10 … 30 V DC
 Current loop 4 … 20 mA
where 4 mA = 0 value; 20 mA = programmed max. value
 Overload up to 20.5 mA, then fault current
 Errors are generated at 3.5 mA or 22.6 mA (programmable)
 Output values: power, flow rate, forward temperature, return temperature, difference
temperature
 Maximal cable length 10 m (acc. to EN 1434)
 Electrical isolated
To use the analogue output module an external power supply is necessary.
The outputs are marked “1” and “2” on the terminal strip with the respective polarity “+” and “-”.
