EM-231-Analog-Input-Module

This is to announce two additional analog expansion modules for SIMATIC S7-200:
EM231 with 8 analog inputs and EM232 with 4 analog outputs.
The dimensions are the same as those of the existing analog expansion modules EM231 and EM232. The new analog expansion modules each occupy one slot for expansion modules in the CPU. The new analog modules permit a larger number of analog channels.

EM231 analog module, 8 analog inputs
EM232 analog module, 4 analog outputs
