Mitsubishi Electric MELSEC-A/QnA Series - Chapter 5 Multiplexer Replacement; A60 Mx; Performance Comparison

5 MULTIPLEXER REPLACEMENT
5 - 1
The multiplexer module is designed especially for channel extension of the analog-digital converter
module A616AD.
Analog input signals (voltage/current) taken by the multiplexer module are output as analog output
signals (voltage) to the A616AD.
For this reason, the I/O characteristics and the maximum resolution of the multiplexer module are
adjusted to be the same as the voltage input specifications of the A616AD.
Check the set range in each channel of the existing multiplexer module to estimate the I/O
characteristics and the maximum resolution.
As regarding A60MX non-isolated multiplexer module, consider replacement using multiple Q68ADV/I.
