The GW Instek DAQ-900 solid state relay module is meant as an expansion for the GW Instek DAQ-9600. The DAQ-900 is a 20 channel universal multiplexer that provides two groups of 10 2-wire channels; these channels are switchable to high and low inputs. An advantage of this module is that it has a built-in cold junction reference, which can reduce errors while measuring thermocouples.
