The 2N EntryCom IP Wiegand isolator is an accessory device for IP-based intercom systems, specifically designed for galvanic isolation of Wiegand signals in access control systems. It is used to prevent electrical interference and voltage differences between various system components, especially when multiple manufacturers or different networks are interconnected. Galvanic isolation protects connected devices from damage caused by voltage spikes and enables stable, interference-free signal transmission. The isolator is designed for use in professional security and access control systems, where signal transmission reliability is critical.

Wiegand technology is a standard for transmitting data from access control card readers to control devices. Data are transmitted over two lines (Data 0 and Data 1) in the form of pulses. The 2N Wiegand isolator performs galvanic isolation of these signals, thereby breaking the electrical connection between sender and receiver without compromising data integrity. This is particularly important when connecting systems from different manufacturers or with different grounding potentials.

Applications include integrating access control systems into existing IP intercom systems, especially in multi-storey buildings or buildings where different security systems from various suppliers are installed. The isolator ensures that signals between card readers and control devices are transmitted without interference, preventing malfunctions or false alarms. It is suitable for applications in office buildings, residential complexes, industrial facilities, and other installations where secure and reliable access control is required.

Functions and features in detail include galvanic isolation of Wiegand signals, support for standard Wiegand protocols, and compatibility with IP-based intercom systems from the 2N EntryCom IP series. The isolator operates without additional power supply, as it is powered through the signal lines. The terminal clamps allow for easy and secure connection of Wiegand cables. The design is compact and intended for mounting in standard distributors or enclosures.

Technology explained simply means that the isolator interrupts the electrical connection between two Wiegand end devices without impairing data transmission. This is achieved through optical or inductive coupling, which transmits signals without direct electrical contact. This prevents voltage differences caused by different grounding or power supply systems from damaging connected devices. Galvanic isolation is a standard in industrial electronics to enhance system reliability and lifespan.

Compatibility and accessories include use with IP intercom systems from the 2N EntryCom IP series. The isolator is specifically developed for integration into such systems and enables connection of Wiegand-compatible card readers to the intercom control devices.

Installation and mounting is done by connecting to the Wiegand cables between card reader and control device. The terminals are designed for connection with standard cables. No additional power supply is required. Mounting is performed in a suitable enclosure or distributor, ensuring environmental conditions (temperature, humidity) comply with technical specifications. Installation must be carried out by qualified personnel who adhere to electrical regulations and safety requirements.

“Operational advantages” include enhanced system stability and reliability. Galvanic isolation prevents interference and false alarms, reducing maintenance needs and increasing operational safety. Easy installation and compatibility with existing systems facilitate integration into current infrastructures. The isolator contributes to the longevity of connected devices by preventing damage from voltage spikes.

Wiegand isolator is the central product term describing the device’s function. Galvanic isolation is the core function ensuring stability and safety of signal transmission. IP intercom system is the target environment in which the device is used. Access control is the application area where the device fulfills its function. Wiegand technology is the underlying data transmission method supported by the device. Signal transmission describes the process enabled by the device, without direct electrical connection between devices.

Compatibility is limited to the 2N EntryCom IP series, as stated in the manufacturer’s description.
