Differences Between Series A
and Series B Analog Modules
The following lists major differences between series A and series B
analog modules.
Series A
None
No off position available. Module
produces either 2V or 4mA, dependent
upon the range selected, until module is
configured.
4mA output until module is configured
4 20mA user configurable
0 20mA user configurable
2V output until module is configured
10V user configurable
0-10V user configurable
4mA output until module is configured
4 20mA user configurable
0 20mA user configurable
2V output until module is configured
10V user configurable
0-10V user configurable
CSA certified
CSA Class I, Division 2, Groups A, B,
C, D certified
UL listed
Appendix
Series B
This bit is set when all bits in the
configuration register are 0 (unconfigured
state).
Off position now produces 0V or 0mA,
dependent upon range selected, until
module is configured.
0mA output until module is configured
4 20mA user configurable
0 20mA user configurable
0V output until module is configured
10V user configurable
0-10V user configurable
0mA output until module is configured
4 20mA user configurable
0 20mA user configurable
0V output until module is configured
10V user configurable
0-10V user configurable
