Relay matrix modules
More test points? No problem!
With the Matrix modules, you can easily duplicate the standard test outputs to the required number of test points. The test program allows you to flexibly define which points are tested—entirely according to your requirements.
All relays can be switched individually, provide maximum flexibility when combining test points. This allows you to test not only between two points, but also between several points simultaneously – efficiently and in a time-saving manner.
For your safety , each test point safety additionally discharge with a switchable discharge . This means reliable testing with maximum protection.

Relay matrix modules: Precision and flexibility for your tests
Our relay matrix modules are the perfect solution for demanding test and measurement applications. They enable precise switching of test points, flexible combination of measurement circuits, and safe execution of high-voltage tests.
Highest precision thanks to modern relay technology
Depending on the application, we use electromechanical relays or reed relays.
Reed relays in particular are ideal for switching extremely low levels—perfect for sensitive signals such as sense voltages in resistance measurement. For you, this means:
- Reliable measurement results
- Precise switching operations
- Maximum flexibility
Two-wire or four-wire technology the choice is yours
- Two-wire technology: Simple and efficient, comparable to a multimeter.
- four-wire technology: Essential for precise resistance measurements.
Additional sense wires eliminate the influence of relay contacts and wire resistance—for maximum accuracy in low-resistance measurements.
Test voltage application check – safety
Absolute process reliability is essential for high-voltage testing. Our solution:
- Voltage measurement directly on device under test
- Contact monitoring for reliable testing
This ensures that the TEST VOLTAGE is actually applied TEST VOLTAGE DUT – for maximum safety.
Integrated discharge protection for the operator
Test objects Save energy Save certain tests. Our modules provide:
- Switchable discharge test point
- Automatic discharge idle mode
- discharge test points and to earth (PE)
This prevents dangerous residual charges and reliably protects the operator.
Cascading – Test points without limits
Do you need a lot of test points? No problem:
- Any number of modules can be combined
- Intelligent mix of two-wire and four-wire technology
Simple control
The integrated control electronics communicate via CAN bus withprotocol for seamless integration into your test device.
