Visit my online shop at https://mXion.de/ for better prices! You can purchase an mXion TLSpro here purchase (suitable for all gauges, all voltages). You can find more information in the operation manual => https://www.micron-dynamics.de/sitecake-content/mXion%20TLSpro.pdf The TLSpro is a modern twilight or temperature switch. It is supplied with a brightness sensor, so that a brightness switch can be easily implemented with it. The operating voltage is irrelevant. The relay has led out all 3 outputs separately and separately, so that external voltages can be switched with it. The TLSpro also offers an "IP" signal output, which makes it possible to operate the contact inputs of a decoder or other mXion modules. The changeover relay makes it possible to switch on or off when the light is br.
