DAQ-900
20-Channel Universal Multiplexer (Solid State Relay)

• Scanning speed up to 450 channels per second
• 2-wire and 4-wire scanning
• Built-in temperature cold junction reference
• 120V switching

The DAQ-900 is a solid-state relay module that provides two groups (A/B) of 10 2-wire channels each.

All 20 channels are switchable to high (HI) and low (LO) inputs, providing fully isolated inputs for the built-in digital meter or external instruments.

During 4-wire resistance measurements, the channels of group A are automatically paired with the channels of group B to provide power and sense connections.

The module has a built-in cold junction reference, which can greatly reduce errors caused by thermal gradients when measuring thermocouples.

DAQ-901
20+2 Channels Universal Multiplexer (Armature Relay)

• Scanning speed can reach 80 channels per second
• 2-wire and 4-wire scanning
• Built-in temperature cold junction reference
• 300V switching
• The extra 2 channels can directly measure current (1A/per CH)

The DAQ-901 is a comprehensive multiplexer for general scanning.

The same module can mix 2-wire and 4-wire channels; at the same time, the additional 2 current input channels can be used for AC and DC current measurement without external shunt resistors (maximum 1A per channel).

With a total of 22 channels, intensive multi-function switching, and a scan rate of up to 80 channels per second, the DAQ-901 is suitable for various data acquisition applications.

DAQ-903
40-Channel Single-Ended Multiplexer

• Scanning speed can reach 80 channels per second
• Single-wire switching is suitable for common-low applications
• Built-in temperature cold junction reference

The DAQ-903 can switch 40 single-wire inputs per module.

It can be used for common-low applications such as battery testing, component characterization, and desktop testing.

The low-voltage connection is isolated from the ground and can be floated up to 300V.

DAQ-903 also supports all 2-wire internal measurements except current.

DAQ-904
4 x 8 2-Wire Matrix

• 3ms switching speed
• 32 2-wire intersections
• 300V, 1A switching
• Up to 96 crosspoints (3 slots)

The DAQ-904 module can provide the most flexible connection path between your DUT and the test system, allowing different test instruments to be connected to multiple points on the DUT at the same time.

The DAQ-904 can connect rows and columns of multiple modules to build larger matrices, such as 8 x 8, 4 x 16, etc.

Up to 96 crosspoints can be built in a single instrument.

DAQ-909
8+2 Channels High Voltage, High Current Multiplexer

• 3ms switching speed
• DC voltage 600V, current 2A
• 2-wire and 4-wire scanning
• Additional 2 channels can directly measure current (2A/per channel)

DAQ-909 is a multiplexer specially designed for high voltage, providing 8 channels for DC 600V / AC 400Vrms voltage measurement.

The additional 2 current input channels can be used for AC and DC current measurement, external shunt resistors are not required (maximum 2A / per channel).
