Current slide {CURRENT_SLIDE} of {TOTAL_SLIDES}- Best Selling in Alarm Systems
The item work fine from DC tension 8-40V. Very good stability. The PCB board looks good, it's a qualitative product. Do not connect the alternating voltage supply, risk damaging the product. The product was installed somewhere where the 2G reception was just -105dBm. I mean, a very poor 2G reception ... with just a signal bar on the phone ... However, the network on the RTU5024 is always present, never disconnected. The product only works with SIM cards in 2G. The relay capability is very good for low signals, but at 250Vac the maximum current of 5A must not be exceeded. Or, a max. 15A current for a load of 14 volts DC should not be exceeded. Alternatively, order the coil of an external big relay if you need to order large loads (large electrical pumps etc.).

Iโm using it to start the fuel heater (webasto) remotely. Works like a charm!
