Relay Expanders
Arxtron’s Relay Expanders are high-density, fixture-mounted relay modules that significantly boost the switching capacity of ICT systems. Designed for seamless integration at the fixture level, they allow for efficient routing of test signals and power distribution without overloading the tester’s native resources.
Whether you’re managing multi-board panelized DUTs or expanding digital and analog test coverage, these relay expanders provide flexible, programmable switching using I2C communication. They’re particularly well-suited for complex test environments that demand reliability and compact layout compatibility, such as with the Keysight i3070.
Applications & Benefits

Power Control
Efficiently switch power rails across high-density board setups
Available in 150Ω and 0Ω Options
Supports both standard and low-resistance signal paths.
Fixture-Compatible
Designed for seamless integration with no interference to probe fields or structural components.
