Power supply (default +24Vdc) must be connected to pin 7 (+) and pin 8 (0Vdc / common)
Analog input signals should be connected to pin 3 (+) and 0 Vdc/common.
Analog output signals are available at pin 2 (+) and 0 Vdc/common.
Signals are according to one of the Bronkhorst High-Tech B.V. standards. The model configuration contains a
code, describing the input/output signals.
Notes:
a. Max. load current output (0 – 20 mA / 4 – 20 mA sourcing) : 375 Ohm
b. Min. load voltage output (0 – 5 Vdc / 0-10 Vdc) : 2 kOhm
c. Input load resistance (voltage 0 – 5 Vdc / 0-10 Vdc) : 1M
d. Input load resistance (current 0 – 20 mA / 4 – 20 mA) : 250 Ohm
The power supply of the modules 23, 24 and 25 is factory set to default +24Vdc.
