Rigol MC3324 MIX Module 20-voltage-channel+4-current-channel Mixed Multiplexer . 24 channel multiplexer module for use with M300 DAQ System Mainframe and MC3065 DMM module. This card has 20 voltage channels configurable for 2 or 4 wire measurements and 4 current only measurement channels. The M3TB24 is the mating terminal block for this module. MC3324 (24-Channel Multiplexer)
The MC3324 is a mixed multiplexer with 20 voltage channels and 4 current channels. All 20 voltage channels switch both HI and LO inputs, thus providing fully isolated inputs to the DMM module, and is divided into two banks (called A and B) of 10 two-wire channels each. When making 4-wire resistance measurement, the instrument automatically pairs channels of A bank and B bank. All channels are break-before-make. You can close multiple channels on this module only if you have not configured any channel to be part of the scan list. 4 current channels are used in combination with the DMM module to measure DC current or AC current. All channels are break-before-make. In any case, you cannot close multiple channels on this module. This module can be connected with MC3065 (DMM Module, if MC3065 is currently inserted).
