Relay module PU1/HV/24V AWZ517

Universal relay module for alarm and control systems

The PU1/HV/24V (AWZ 517) relay module is a component designed for use in low-voltage installations. It is used to control various types of circuits, signal states in alarm systems, access control, and to protect devices with higher current consumption. Thanks to the provided galvanic isolation, the module protects against interference and the influence of voltages from different sources. This is a solution for both professionals involved in electrical installations and security systems, as well as end-users who need a reliable control element.

Construction and functionality

The module is characterized by a compact open-frame design, which facilitates its installation inside enclosures and power supplies. The possibility of mounting with self-adhesive tape or screws provides flexibility during installation. Equipped with a single relay with three contacts (C/NC/NO), it allows for the implementation of various control functions – from simple on/off switching to more advanced applications requiring changing the state of the contacts. An LED indicates the operating state of the relay, which facilitates diagnostics and monitoring. A 6.3A fuse protects the circuit against overloads and short circuits.

Key parameters and applications

The module is adapted to work with a coil voltage in the range of 20÷32V DC/AC, which makes it compatible with a wide range of power sources. The relay can operate with a load of up to 6A at 30V DC or 250V AC. Thanks to this, the module finds application in many areas:

• Alarm systems: Controlling sirens, door locks, etc.
• Access control: Cooperation with card readers, magnetic locks.
• Home automation: Controlling lighting, heating, electrical appliances.
• Industry: Controlling machines and production equipment with low power consumption.
• Buffer power supplies: Expanding the functionality of power supplies by adding the ability to control external circuits.

Additionally, the module has overvoltage protection thanks to the fuse and provides galvanic isolation between the control and loaded circuits, which increases safety and system reliability.
