This application module may seem small but has great performance – it all depends on your programming skills. Now you can create your own custom application without having to do the hardware. All buffered entrances and exits are pre-made for you. The module has a built-in LED, a relay output and a buzzer. Make your own automation, controller, car application... All you need is one of our programmers like Vm134 or K8076. 9 free programmable I/O (4 in, 5 outputs) • Pic16F630 microcontroller from Microchip® On-Board • LED indication for power supply and relay output • 1 free programmable LED indication • Built-in mini-buzzer for audio signals • On-Board Icsp™ connector for programming • Pic™ programmer supports Pic16F630. Power Supply: 12V DC (unregulated) / 100Ma • 4 inputs (voltage sensing inputs) • Input signal voltage: 5 - 24Vdc, @ 4K7 • 4 Npn transistor outputs (open collector, immersion outputs).: •• Transistor output current: Max. 100Ma each • • Direct 12V relay drive possible (no need for protection diode) • 1 relay output with no/Nc connector (2A) • McCu speed: Fixed 4Mhz internal oscillator • Dimensions: 80 X70 X 25Mm / 3.15 X 02.75" X .
