L5504AMP Schneider Clipsal C-Bus Dimming Interface 4 Way 0-10V DC Output Module DIN Rail 240V Unit
The L5504AMP is a DIN rail mounted analogue output unit for the Clipsal C-Bus control and management system. It provides four independent output channels that deliver a zero to ten volt DC signal to connected devices downstream.
This unit serves as the bridge between a lighting control network and the luminaires themselves, driving dimmable electronic ballasts and LED drivers that accept 0 to 10V control inputs. The four-channel design offers an optimal balance: dense enough to avoid needing individual devices per circuit, yet compact enough to remain economical for projects with small lighting groups.
Mounted on DIN rails within distribution boards, the unit allows low-voltage control wiring to exit the panel alongside mains circuits supplying the luminaires, keeping both functions together for commissioning and maintenance.

Important Engineering Consideration: The 0 to 10V dimming interface controls lighting levels, not power. Mains supply to each luminaire must be independently switched and protected. Assuming the module turns lighting off can result in luminaires dimming to minimum but remaining faintly lit.
Control cables, while low voltage, are not immune to interference and should be run separately from mains conductors where practical. During commissioning, outputs should be verified channel by channel, as mis-mapped channels can appear as programming errors but are actually wiring issues.
Minimum and maximum levels require attention since drivers vary in their extinction points. A scene fading to zero may leave residual glow that cannot be resolved through C-Bus programming alone. When multiple modules share a board, record both C-Bus network load and addressing.
- Commercial Office Floors: Primary application for luminaires with dimmable ballasts or LED drivers, enabling central control for daylight regulation and scene setting
- Retail and Hospitality Interiors: Creates layered lighting zones that can be reprogrammed as layouts change
- Conference and Teaching Spaces: Four-channel grouping establishes presentation and discussion states from single control points
- Hotel Public Areas: Enables independent level control for different space areas from one network
- Retrofit Projects: Control wiring can often reuse existing cabling between boards and luminaires while switching arrangements are updated
