M-MFN02 screen power control and sensor functions
The Mooncell M-MFN02 is a multifunction accessory card for LED display systems. It adds switching control, automatic brightness support, timing/delay functions and audio output alongside the receiving-card chain. External modules can provide temperature, humidity and smoke monitoring.
For installation, distinguish the low-voltage card supply from the separately listed voltage/current entries, whose circuit conditions are not defined in the PDF. The document also repeats two different working-temperature ranges. These limitations are shown below so they are resolved before wiring or environmental selection.
Technical specifications
| Parameter | Specification |
|---|---|
| Model | Mooncell M-MFN02 multifunction card |
| Network connections | 2 RJ45 ports, shown in the interface diagram, for connection within the receiving-card chain |
| Serial control | RS232 connection to the control computer |
| Power-control channels | 8 switch-control channels |
| Light sensors | Supports connection of up to 4 light sensors for automatic brightness adjustment |
| Environmental monitoring | Distribution-box temperature detection; external temperature/humidity and smoke modules supported |
| Audio | Integrated audio output |
| Timing | Timer/delay functions |
| Card operating voltage | DC 3.5–5.5 V |
| Power consumption | 5 W |
| Temperature entries — unresolved | The PDF lists both −10 to 65°C and −20 to 75°C under the identical label “Working Temperature.” It does not distinguish operating from storage temperature. |
| Humidity | 0–95%, as listed in the PDF |
| Other voltage/current entries | The PDF separately lists “Power Supply Voltage” 0–250 V and “Power Supply Current” 0–3 A without identifying their circuit or load conditions. These do not replace the card’s DC 3.5–5.5 V operating-input specification. Confirm switch/load ratings before wiring. |

Frequently asked questions
What does the M-MFN02 card add to an LED screen system?
It adds eight power-control channels, sensor connections, timing/delay functions and audio output. It connects with receiving cards through RJ45 and supports RS232 control from a computer.
How many brightness sensors can it use?
The specification lists support for up to four light sensors for automatic brightness adjustment. The light sensors are not included with the card according to the packaging section.
Where can the card be connected in the receiving-card chain?
The PDF permits installation between the sender and first receiving card, between receiving cards or after the last receiving card. It also describes a direct serial connection to the computer.
Can the card itself be powered from 250 V?
No. The stated card operating voltage is DC 3.5–5.5 V. A separate 0–250 V table entry does not identify its circuit or load conditions and must not be interpreted as the card’s supply input. Have the switching connections and ratings confirmed before wiring.
What operating temperature should be used for selection?
The PDF repeats “Working Temperature” for both −10 to 65°C and −20 to 75°C, without explaining the difference. Confirm the applicable operating range rather than assuming one is a storage rating.
