9. Analogue and digital I/O configuration
9.1 Analogue output (menu 6.6.4)
Either NGR current I
NGR
or NGR resistance R
NGR
can be assigned to the analogue out-
put. A voltage or current signal proportional to the measured value is applied to the
output. The following settings are possible:
Mode (menu 6.6.4.1)
0…20 mA Permissible load ≤ 600
4…20 mA Permissible load ≤ 600
0…400 µA Permissible load ≤ 4 k
0…10 V Permissible load ≥ 1 k
2…10 V Permissible load ≥ 1 k
For further information, refer to refer to „X1: Analogue output“ on page 32.
Function (menu 6.6.4.2)
Set which measured values are assigned to the analogue output. Setting options:
I
NGR
R
NGR
(HRG devices only)
9.2 Digital outputs (Q1, Q2)
The digital outputs can draw current (sink).
The current rating for the Open-Collector output is 300 mA for each output.
Since the "+24 V" connection can only provide 100 mA, it might be required to use an
external voltage supply (+24 V) for the relays
