What Is a One In Multiple Out Junction Box?
One in multiple out junction box is a modular device designed to split a single power input into multiple outputs safely and efficiently.
It enables clean and organized electrical distribution within control cabinets, lighting panels, and automation systems.
The structure typically includes:
- One main input terminal for the power source.
- Multiple output terminals that distribute power to devices or circuits.
This design eliminates the need for messy parallel wiring and reduces connection errors.
By integrating modular terminals, engineers can expand circuits easily without modifying the cabinet layout.
How Multi-Channel Splitter Design Improves Efficiency
Multi-channel splitters allow parallel distribution, cutting down installation time and cable length.
Splitters organize branches logically, supporting rapid troubleshooting and easy scalability.
- Reduce wiring complexity by centralizing connections.
- Enable clear identification for each output.
- Support efficient maintenance and future expansion.
| Merkmal | Multi-channel Splitter | Traditionelle Verdrahtung |
| Distribution | Multi-output | Single/limited |
| Expansion | Easy, modular | Schwierig |
| Wartung | Simple, organized | Complex |
| Wirkungsgrad | Hoch | Lower |
Compared to traditional terminal rows, this splitter ensures higher wiring density and consistent electrical performance under industrial conditions.
Wiring Diagram and Connection Examples
Die 1 in multiple out terminal block concept follows the same principle as AOSI’s Power Distribution Module series — a centralized input line feeding multiple branch outputs.
Typical Wiring Diagram:
- Input: 24 V DC or 230 V AC main feed line
- Outputs: multiple terminals for PLC modules, sensors, actuators, or lighting circuits
Example Applications:
- Connecting PLC power rails to multiple I/O modules
- Supplying 24 V power to several contactors or relays
- Distributing single power feed to LED driver groups
- Unser Stromverteilungsmodul series shares the same modular concept as the One In Multiple Out Junction Box — combining compact size, multi-channel outputs, and push-in connection for faster, safer, and cleaner wiring in industrial control cabinets.
Applications in Industrial Power Distribution
Junction boxes have versatile industrial applications, such as:
- PLC panel distribution of sensor/actuator power.
- Lighting circuit splits for multi-zone control.
- Renewable energy cabinets managing solar or battery outputs.

FAQs — One In Multiple Out Junction Box
A1: A one in multiple out junction box is a modular device that takes a single input (power or signal) and distributes it to several output terminals. Internally, it uses conductive busbars or PCB traces to ensure each output receives the same input voltage or signal. This structure is ideal for organizing complex wiring in control panels, lighting systems, and industrial automation, reducing clutter and improving safety.
A2: Multi-channel splitters centralize wiring, reduce cable length, and make troubleshooting easier. They support modular expansion, so you can add or remove outputs as needed. This not only saves installation time but also allows for future upgrades without major rewiring.
A3: Consider the number of outputs required, wire gauge, rated current/voltage, mounting method (DIN rail, panel, wall), and environmental protection (IP rating). For example, PTFIX is suitable for DIN rail mounting and supports up to 18 outputs, while KV225 is ideal for panel mounting.
A4: Yes, for outdoor or humid environments, choose junction boxes with IP44, IP65, or higher ratings. These models feature sealed gaskets and corrosion-resistant materials to protect against moisture and dust.
A5: They are used in PLC control panels, lighting distribution, HVAC systems, renewable energy cabinets, and anywhere multiple circuits need to branch from a single source.
A6: Yes, many models support modular expansion—additional output modules can be snapped on or plugged in as needed. This flexibility allows for easy system upgrades or reconfiguration without major rewiring.
