7.8 RAD-DAIO6-IFS - analog/digital extension module
with six channels
The RAD-DAIO6-IFS analog/digital I/O extension module has a total of six channels. The
device can process two digital input and output signals as well as one analog input signal
and one analog output signal. All inputs and outputs are electrically isolated from one an-
other, from the supply voltage, and from the electronics.
Two digital inputs
The digital inputs process voltages of 0 V ... 50 V AC/DC at the low voltage input and volt-
ages of 0 V ... 250 V AC/DC at the high voltage input.
Two digital outputs
The digital outputs are designed as floating relay contacts (changeover contacts). The
switching capacity is 2A at 250VAC/24VDC.
Analog input
The analog input can process standard signals of 0/4 mA ... 20 mA. A supply voltage of at
least 12 V DC is available at connection terminal block PWR
1
for passive sensors.
Analog output
The analog output is designed as an active output. You can select a current signal of
0/4 mA ... 20 mA or a voltage signal of 0 V ... 10 V.

WARNING: Risk of electric shock
Use the same phase for digital inputs and outputs. The isolating voltage between the
individual channels must not exceed 300 V.
Use either the current or voltage output at the analog output.
