Relay matrix modules
More test points? No problem!
With the matrix modules, you can easily multiply the standard test outputs to the required number of test points. The test program allows you to flexibly define which points are tested – exactly according to your requirements.
All relays are individually switchable and provide maximum flexibility when combining test points. This allows you to test not only between two points, but also between several simultaneously – efficiently and time-saving.
For your safety, each test point is additionally equipped with a switchable discharge. This means reliable tests with maximum protection.
Key Facts:
- High voltage AC up to 6 kV | DC up to 8.5 kV
- 6 / 12 / 24 test points in two-wire technology
- 3 / 6 / 12 test points in four-wire technology
- Built-in discharge
- Infinitely cascadeable – scalable matrix solution
- Flexible Matrix Architecture
- CAN bus or digital interface
- Relay Cycle Counting
- Housing variants: 19" rack, desktop, control cabinet

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. This means for you:
- Reliable Measurement Results
- Precise Switching Operations
- Maximum flexibility
Two-wire or four-wire technology – You decide
- Two-wire technology: Simple and efficient, comparable to a multimeter.
- Four-wire technology: Indispensable for precise resistance measurements.
Additional sense lines eliminate the influence of relay contacts and line resistances – for maximum accuracy in low-resistance measurements.
Test Voltage Contact Control – Safety Guaranteed
In high voltage tests, absolute process reliability is crucial. Our solution:
- Voltage feedback measurement directly at the device under test
- Contact monitoring for reliable tests
This ensures that the test voltage is actually applied to the DUT – for maximum safety.
Built-in Discharge – Protection for the Operator
Devices under test store energy after certain tests. Our modules provide:
- Switchable Discharge per Test Point
- Automatic Discharge in Idle State
- Discharge between test points and to earth (PE)
This prevents dangerous residual charges and reliably protects the operator.
Cascading – Unlimited Test Points
Do you need many test points? No problem:
- Any Number of Modules Can Be Combined
- Intelligent Mix of Two-Wire and Four-Wire Technology Possible
Simple Control
The built-in control electronics communicate via CAN bus with CANopen protocol – for seamless integration into your test device.
