The GW Instek DAQ-900 for the DAQ-9600 data logger mainframe is a solid-state relay module that provides two groups (A/B) of 10 2-wire channels each. All 20 channels can be switched to high (HI) and low (LO) inputs, providing fully isolated inputs for the built-in digital meter or external instruments. For 4-wire resistance measurements, Group A channels are automatically paired with Group B channels to provide current and measurement connections. The module has a built-in cold junction reference that can significantly reduce errors caused by thermal gradients when measuring thermocouples.
Product features:
- Sampling speed of up to 450 channels per second
- 2-wire and 4-wire sampling
- Built-in temperature cold junction control
- 120 V circuit
