## Summary description

Audac ARJ03P is a compact network junction box in green for organizing and protecting network terminations. Dimensions are 61 × 40 × 48 mm, suitable for mounting RJ connectors and short cable runs. Single-unit pack designed for neat cable routing and secure enclosure of small Ethernet or communication joints in installations.

## Long description

Audac ARJ03P is a compact network junction box in green, sized 61 × 40 × 48 mm, designed to organize and protect RJ45-based network terminations and short cable runs. The unit integrates three RJ45 connectors configured as BUS IN, BUS OUT and a third port for connecting a remote in- or output module. The enclosure includes two termination jumpers to terminate communication and audio pairs at their characteristic impedance and a terminal block for connecting an external +24 V DC supply that is routed to RJ45 Pin3 (+) and Pin6 (GND). The housing is made of unbreakable plastic and is suitable for mounting on Mini DIN rails.
Advantages
The ARJ03P provides a compact, single-unit solution for splitting and joining twisted-pair databus lines while maintaining signal integrity through selectable pair termination. Built-in power distribution allows applying an external +24 V DC supply to remote modules without modifying the cable infrastructure. Rugged plastic housing and DIN rail compatibility enable secure, space-saving installation in equipment cabinets and intermediate mounting points.
Suitable for
 Expanding communication or audio busses that use RJ45 connections
 Connecting a remote in- or output module to an existing bus
 Supplying external +24 V DC to remote modules over the bus
 Short cable routing points and protected RJ45 terminations in installations
Key specifications
 Dimensions: 61 × 40 × 48 mm
 Color: green
 Connectors: three RJ45 ports (BUS IN, BUS OUT, module port)
 Termination: two jumpers for terminating communication (Pins 4 & 5) and audio (Pins 7 & 8) pairs at 120 Ω
 Power input: terminal block for external +24 V DC; +24 V available on RJ45 Pin3 (+) and Pin6 (GND)
 Mounting: Mini DIN rail compatible
 Housing: durable, impact-resistant plastic
How to use
Mount the ARJ03P on a Mini DIN rail or in a suitable enclosure at the desired cable routing point. Connect the incoming databus to the BUS IN RJ45 and the outgoing segment to BUS OUT. Plug the remote in- or output module into the third RJ45 port. If required, fit the termination jumpers to terminate the communication pair (Pins 4 & 5) and/or the audio pair (Pins 7 & 8) at 120 Ω to reduce signal reflections. Connect an external +24 V DC supply to the terminal block to provide power over the bus; verify polarity so that +24 V is presented on RJ45 Pin3 and ground on Pin6.
Usage recommendations
Use the ARJ03P for short-distance splits and intermediate connection points in twisted-pair databus systems. Enable pair termination only when the device is located at the physical end of a bus segment or when required by the system design. Confirm that the external power source provides the correct DC voltage and current rating for connected remote modules and that grounding practices follow the installation guidelines to avoid ground loops.
