Why Choose 4-Channel LED/OC Module?
- 3 modes in one – open collector output, LED dimmer or RGB/RGBW
- Ideal for smaller projects – 4 powerful channels at a fraction of the cost of a larger module
- Space saving – only 2 modules on DIN rail
Typical Applications
- Tunable White control (warm in the evening, cool during the day)
- RGB backlighting
- 2× or 4× independent LED strips
- RGB showcase lighting
Features
- 4 LED/OC outputs (open collector) configurable as:
- Open collector output – digital outputs
- LED dimmer – works with constant voltage LED lights (e.g., LED strips), frequency adjustable up to 25 kHz (default 587 Hz)
- Tunable white – 2 dimmed outputs for LED strips with warm and cool white
- RGB/RGBW – 3 or 4 outputs for full colour spectrum
- Electrical parameters:
- Maximum current: 6 A DC per channel
- Maximum total load: 16 A
- Maximum voltage: 28 V DC per channel
- Recommended cable length between light and module:
- 30 m for 1.5 mm² cable
- 45 m for 2.5 mm² cable
- Protection class IP20, operating temperature: -20 °C to +55 °C
- Maximum power dissipation: 3 W
- Power supply: 24 V DC ±10%
- Communication: TapHome Bus (connection to Core unit)
- Protection features: Electronic short-circuit and thermal protection
- Terminal type: Screw terminals
- Signal terminals (3.50 mm):
- Wire cross-section: 0.14–1.5 mm² (AWG 30–14)
- Torque: 0.2–0.25 Nm
- Strip length: 6.5–7.5 mm
- Power terminals (6.35 mm):
- Wire cross-section: 0.34–4.0 mm² (AWG 26–10)
- Torque: 0.5 Nm
- Strip length: 7.2 mm
- DIN rail mounting, 2 modules. Dimensions: width 36 mm, height 59 mm, depth 60 mm
Load Calculation Example
For 24V LED strip with 12 W/m power consumption:
- Current per metre: 12 W / 24 V = 0.5 A/m
- Maximum strip length per output: 6 A / 0.5 A/m = 12 m
- For longer strips, use multiple outputs
- For RGB/RGBW strips, divide total power by 3 or 4
Total module capacity: 16 A × 24 V = 384 W, corresponding to maximum 32 m of LED strip with 12 W/m power consumption.
