Tester relè Voltcraft RT-100 — per testare relè da 12 V a 230 V

The Voltcraft RT-100 relay tester is a compact, single-piece device designed to verify the operation of electromechanical relays across a wide voltage range from 12 V to 230 V. It provides a simple way to check coil continuity, confirm switching action and observe contact operation without dismantling the relay from its socket. The lightweight tester is intended for workshop diagnostics, maintenance checks and field service tasks where quick validation of relay performance reduces troubleshooting time.

Advantages

The tester supports a broad input voltage range, enabling use on automotive 12 V systems as well as industrial and domestic supplies up to 230 V. Its single-unit design allows direct connection to relay pins for immediate functional testing, and visible indications make it straightforward to determine whether coils and contacts are operating correctly. The compact build makes the device portable for on-site work and routine servicing.

Suitable for

• Workshop relay diagnostics and repair
• Maintenance checks in industrial control panels
• Field service and onsite troubleshooting
• Testing relays in automotive and marine electrical systems
• Educational and training demonstrations of relay operation

Key specifications

• Operational voltage range: 12 V to 230 V AC/DC
• Compatibility: electromechanical relays with standard pin layouts
• Functions: coil continuity check, switching verification, contact operation indication
• Form factor: compact, single-piece handheld unit
• Typical use environment: workshop, industrial, field service

How to use

Connect the Voltcraft RT-100 to the relay by aligning its contacts with the relay pins or inserting the relay into the tester as applicable. Apply the appropriate supply voltage within the 12 V to 230 V range. Observe the tester indications while energising the coil to confirm switching action and check contact operation. For safety, ensure that the supply is disconnected before making or changing connections and follow standard electrical safety procedures when working with live circuits.

Recommendations

Use the tester within the specified voltage range and verify compatibility with the relay pinout before testing. When working on high-voltage systems, use insulated tools and appropriate personal protective equipment. Store the device in a dry environment and inspect contacts for cleanliness to maintain reliable testing results.
