– 450 ch/s scanning

– Two- and four-wire scanning

– Built-in thermocouple reference junction

– 120 V switching

The DAQM900A module is divided into two banks of 10 two-wire

channels each. All 20 channels switch both HI and LO inputs, thus

providing fully isolated inputs to the internal DMM or an external

instrument. During 4-wire resistance measurements, channels

from Bank A are automatically paired with channels from Bank B

to provide the source and sense connections. The module has a

built-in thermocouple reference junction to minimize errors due to

thermal gradients when measuring thermocouples.
