6ES7 332-5TB00-0AB0
The HART analog output module SM 332; AO 2 x 0/4...20mA HART has the
following properties:
2 outputs in 2 channel groups
Resolution 12 bit (+ polarity)
Measurement type can be selected for each channel:
– Current output with HART
– Current without HART usage
– Channel deactivated
Output range selectable for each channel
– 0...20 mA (without HART usage)
– 4...20 mA
Settings for diagnostics and diagnostic interrupt
– Enable group diagnostics
– Enable/disable diagnostic interrupt
Isolation
– Channels electrically isolated from each other
– Channels electrically isolated from CPU and load voltage L+
Readback capability of the analog outputs
The representation of the analog values is the same as for the analog output
module SM 332; AO 4 x 0/4...20mA, see Section 3.1.3. The resolution of the
output value for the HART analog output module is, however, 12 bits.
