Installation of the 12 volt relay module DIN

The 12 Volt DIN relay module is a compact dual-channel power and switching module for controlling 12 V DC devices up to 1 A per output (potential-free). Thanks to integrated relays and potential-free inputs, the module offers reliable switching and power supply functions for a wide range of automation and control applications.

Main functions:

• Two independent outputs (A and B): Each output provides:

• Potential-free inputs (A and B): Control of relays via external potential-free contacts, e.g., for switches, sensors, access control systems, or automation controls.
• Safe and isolated switching: Internal relays ensure safe operation and galvanic isolation between control signals and connected devices.

The VT12 DIN relay module is suitable for:

• Power supply and switching of 12 V DC devices such as electronic locks, LEDs, solenoid valves, fans, alarm systems, or relays.
• Integration into access control, automation, and security systems via potential-free contacts.
• Simplifying low-voltage wiring and control, replacing separate relays or power modules.
• Supports two independent channels, enabling control of multiple devices with a single unit.

Due to its versatility, it is ideal for security systems, building automation, smart home solutions, and industrial control cabinets.

Compatible Didactum systems: 550T and 300T both feature potential-free contacts and are compatible with the relay module (I/O).

Read and carefully follow the safety precautions listed below before working with the VT12 relay module.

• This device must be installed by qualified electricians only. Such work should not be carried out until these instructions have been read in full.
• Before any visual inspection, testing, or maintenance work on this device, all power sources must be disconnected. Assume that all circuits are live until they have been completely de-energized, tested, and labeled. Pay particular attention to the power supply system design. Consider all power sources, including the possibility of backfeed.
• Disconnect the power supply to the voltmeter and the device in which it is installed before starting any work.
• Always use a voltage tester with the appropriate voltage rating to ensure that the power supply is completely disconnected.
• Wear the required personal protective equipment (PPE) and follow all applicable safety regulations for electrical work.
• Before closing all covers and doors, carefully check the work area for tools and objects that may be inside the unit.
• When removing or installing panels, take care to ensure they do not protrude into the live busbar. Avoid handling the panels, as this could result in injury.
• The proper functioning of this unit depends on correct handling, installation, and operation. Failure to comply with basic installation requirements could result in injury, damage to electrical equipment, or other property.
• The electricity meter should be installed in a suitable electrical and fire-resistant enclosure.
