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
Channels 0 and 1 •
Channels 2 and 3 •
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.
Measuring ranges
Program the measuring ranges in
Table 6- 41
Selected type of measurement
V: Voltage
R-4L: resistance (4-wire connection)
RTD-4L: Thermoresistor
(linear, 4-wire connection)
(temperature measurement)
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
Table 6- 42
Selected type of output
Voltage
