UniPut™ 24 V AC Detection
If 24 V AC is connected to a Uniput™ terminal, then the 24 V AC Detect circuit will detect this and will open
switch SW1. SW1 stays open for the duration of the 24 V AC state. When 24 V AC is removed from the
Uniput™ terminal then the short circuit or open circuit states can again be detected.
Voltage input mode (Active Input)
Note: Input Impedance for Universal Input terminals is 130 kΩ.
Input Impedance for Uniput™ terminals is 40 kΩ.
The 0 … 10 V input is used for Active analog and digital measurements. ‘Active’ means that there is no
current supplied by the CBXi-8R8(-H) for the sensor, as the signal is generated completely by the Sensor.
The ‘mV’ sensor setting gives a value between 0 and 10,000, which represents voltage in mV.
In 0 ... 10V Input Mode, the Uniputs™ configure like this:
Current Input mode (Active Input)
The Current Input is used for 0 ... 20 mA or 4 ... 20 mA Active sensors.
4 ... 20 mA scaling can easily be achieved using CXproᴴᴰ by entering range values in the Point Module
‘Advanced’ parameters.
