IOtech 6222 Block Diagram

The 12 thermocouple input channels of the 6222 are set up in three distinct isolated sections. Channels 1 through 4

share a common (COM) and an isolator; channels 5 through 8 and channels 9 through 12 also have this scenario.

Note 1: Circuits for channel group ‘5 through 8’ and group ‘9 through 12’ look like that of the first group; for which

only one channel is illustrated. Each four-channel circuit has one 24-bit ADC and one CJC.
