Description
GW Instek DAQ-900 is a 20-channel universal multiplexer module (semiconductor relay) for the DAQ-9600 data recording system. The GW Instek DAQ-900 is a semiconductor relay module that offers two groups ( A/B) of 10 channels, each with 2 wires. All 20 channels can be switched to High (HI) and Low (LO) inputs to provide fully isolated inputs for the built-in digital meter or external instruments. For 4-wire resistance measurements, Group A channels are automatically coupled to Group B channels to provide current and sensor connections. The module has an integrated reference reference for reference points that can significantly reduce thermal gradient errors when measuring thermocouples.
