  • [Applications]1. Industrial Control. Valve control, pump station control, unattended industrial control system. 2. Smart Home. Controlling appliances like air conditioner, access control, purifier, water heater, etc. 3. Smart Agriculture. Controlling door curtain motor, air blower, etc. 4. Breeding & Farming. Controlling ventilator, lighting, water supply, feeding system, etc


Question:
When I use 24V power supply and use more than 8 channels at the same time, Relay will automatically shut down after working for a period of time.
Answer:
This is caused by our old version setting the module current limiting resistor too large.
If you encounter this problem during use, you can disassemble the casing yourself and change the resistance to 5.1R or 4.7R, or short-circuit it directly to fix this problem.

Die Lieferung dauerte 11 Tage - weniger als angegebenDie RTU 32CH kommt ohne jegliche Beschreibung, jedoch ist diese auf der Website und im Wiki sehr gut illustriert und funktional beschrieben. Wer dieses Teil kauft, sollte auch über ausreichende Grundkenntnisse zu ModBus verfügen.Ich verwende diese Komponente für die Steuerung von 10 Jalousien (also 20CH + zusätzliche CHs) ohne zusätzliche Snubber mit ModBus Steuerung via ioBroker. Die RTU 32CH läuft seit einem Monat stabil und stürzt nicht ab.Für den Betrieb ist ein externes Netzteil erforderlich (nicht im Lieferumfang enthalten)
