AS-Interface double-data decoupling module S22.5 screw terminal version

AS‑Interface double data decoupling module S22.5 spring-loaded terminal version

With the aid of the S22.5 data decoupling module, the AS-Interface network can also be supplied with 24 V DC or 30 V DC from a standard power supply unit and the transmission of data and power can be realized along one cable.

The combination of data decoupling modules and standard power supply units is therefore a cost-efficient alternative to the service-proven AS-Interface power supply units.

The quality of the data signals and the reliable operation of the AS-i network are not negatively affected as the result.

Features of the data decoupling unit S22.5

• Degree of protection IP20
• Narrow design: 22.5 mm wide
• Screw adapters with screw or spring-type terminals
• Options as single and double data decoupling
• Supply of several AS-i networks with a single power supply unit
• Operation with 24 V DC or 30 V DC, grounded or non-grounded
• Adjustable current limiting up to 2 x 4 A
• Integrated ground fault detection with error log
• Diagnostic LEDs and signaling contacts
• RESET by button or remote RESET

Ground-fault detection

The integrated ground fault detection functions with grounded and non-grounded power supply: The connection of negative pole and ground (upstream from the data decoupling module) customary with 24 V DC power supplies is permitted. A ground fault to the negative or positive pole on the AS-Interface network (downstream from the data decoupling module) is detected and stored as a fault and will be signaled using LEDs and a relay contact.
