thermistors
December 2001
The logic unit and the PLC input/output board PL 410B have analog inputs and

inputs for Pt 100 thermistors.

The PL 410B is available with and without analog inputs.
The current values of the inputs can be requested with Module 9003.
(See "Overview of Modules" on page 5 – 3).
