The analog output unit 0554 3149 (accessory) is suitable for the
output of up to 6 measuring channels in the form of analog signals
(4 to 20mA). The analog output unit is connected to the instrument
via data bus, and the configuration can be carried out via the
control unit.
Power supply
Power is supplied to the analog output box via the measuring box.
The LED of the analogue output unit lights green when the power
supply is correct.
Each individual output channel is thereby assigned to a measuring
channel, the range of the respective measurement channel is
entered and then corresponds to the 4 t 20 mA output of the output
box connected to this channel. If the measurement range is
exceeded 21-22 mA is still output, depending on load. If the
measurement range is fallen short of, the output will be up to 3.5
mA.
The current value is set to 3.5 mA as start value for a non-adjusted
analog output box and for cases of faults.
