Options of wiring the input channels
You can wire the input channels of SM 334; AI 4/AO 2 x 12 Bit in the following combinations:
Channel
Wiring versions
Channels 0 and 1
• 2 x temperature or
• 2 x resistance
Channels 2 and 3
• 2 x voltage,
• 2 x resistance,
• 2 x temperature,
• 1 x temperature and 1 x voltage, or
• 1 x resistance and 1 x voltage
Note
Wiring both a temperature sensor and a resistor to channels 0 and 1 or 2 and 3 is not
allowed.
Reason: Common current source for both channels.

Output ranges of SM 334; AI 4/ AO 2 x 12 bit
The "voltage" output type and "0 V to 10 V" output range are set by default at the module.
You can always use this combination of the output type and range without having to program
the SM 334; AO 4 x 2 Bit in
STEP 7 .
