## Description

This Arduino-based Industrial PLC (Relay Output) features 8 inputs and 6 outputs(digital relay output). As it uses an Arduino Leonardo, you can directly program it through the USB, which is pretty easy to get started. The Spartan controllers are all standarised and can be programmed exactly on the same way. Moreover, the industrial controller offers the possibility of communication using I2C by a master-slave connection that can connect up to 127 modules. All the components are configurable.Board Overview Features With 8 inputs and 6 outputsStandarised controllerEasy to programming Specification Mode Type: Spartan Arduino PLC 16RDAInput / Supply Voltage: 12~24Vdc (Fuse Protection (2.5A) Polarity Protection)Input Rated Voltage: 24VdcRated Power: 30WMax Current: 1.5ASize: 100 * 45 * 115 mmClock Speed: 16MHzFlash Memory: 32kB of which 4kB used by bootloader)SRAM: 2.5KBEEPROM: 1KBCommunication Interface: I2C, USB, RS485 (HD), SPI, TTLOperating Voltage Range: 11.4~25.4VdcOperating Temperature: 0°C~60°COperating Humidity: 10%~90% (No Condensation)Operating Environment: No Corrosive GasStorage Temperature: -20°C~60°CAnalog Input Voltage: 0 ~ 10VacDigital Input Voltage: 5 ~ 24VdcInterrupt Input Voltage: 5~24VdcExpandability: I2C-127 elements, serial port, RS485Digital Isolated Output Relay Voltage: 220Vdc  Documents DatasheetUser Guide Shipping List Spartan Arduino PLC 16RDA (Relay Output) x1
