What is the difference between the ABE7CPA31 and the ABE7CPA31E connection sub-base? Which of them can be used with the M340 BMXAMI0800 and BMXAMI0810 analog input modules connected to a HART device?

Comparing between ABE7CPA31 and ABE7CPA31E wiring diagrams the differences are:

• The Telefast ABE7CPA31E there is a low pass filter for each channel for HART applications.
• It is exclusively for current loop measurements with a 250 ohm shunt is present on each channel.

• But the Telefast ABE7CPA31 can be used with both Current and voltage sensors and can't be used in case HART information is part of the signal to be measured.
