20+2 (Current) Channels Universal Multiplexer (Armature Relay)

Instek DAQ-901 Universal Multiplexer (Armature Relay)

Features and Specifications

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

DAQ-901 is a comprehensive multiplexer for general scanning and is suitable for various data acquisition applications. 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). It has a total of 22 channels, intensive multi-function switching and a scan rate of up to 80 channels per second.

The built-in digital multimeters of DAQ-9600 data acquisition system mainframe can be connected and used via DAQ-900, DAQ-901, DAQ-903 and DAQ-909 multiplexers (all except DAQ-904).
