Relay Barriers
Arxtron’s Relay Barriers are engineered to provide galvanic isolation and controlled switching for in-circuit and functional test environments. These modules are essential for test setups that require high-integrity signal separation—such as ISP programming, analog signal measurement, or when working with mixed-voltage circuits within the same fixture.
Relay Barriers protect test equipment and DUTs alike by enabling or disabling connections via software-controlled relays. Each module comes in multiple configurations—21×2 or 34×2 channels—with selectable resistance values (150Ω and 0Ω), providing unmatched flexibility for your fixture’s switching matrix.
Whether you’re isolating communication lines during flashing or separating analog channels from power circuitry, these relay barriers deliver robust performance in tight, high-throughput production environments.
