The GEVINO opto is certainly the least expensive of the PLCs, nevertheless it has excellent characteristics, such as 12 opto-insulated double-polarity inputs, 6 NPN 6F mosfet outputs, SD card, LIN bus to parallel multiple modules or expansions. Inductive loads, electrostatic discharges and electromagnetic disturbances are protected. It has options such as Ethernet, Wi-Fi, Bluetooth, RTC, RS232, RS485, cellular modem and CE marking.<br>Arduino Zero compatible<br>Supply, inputs, outputs 7V /30V<br>12 opto-isolated inputs, without polarity, with 2 common<br>4 Mosfet 30V 7.6A, with protection diode<br>1 analogue input 4-20mA / 1V / 3.3V<br>1 RS485 port with which to parallel up to 255 gevini, or m-bus, or other.<br>On the front, behind the flap:<br> SD card<br> Micro USB<br> Led inputs, outputs, serial, power<br> Reset button<br>Optional module Ethernet RJ45<br>Optional module WiFi ESP<br>48 Mhz, 32-bit ARM Cortex - M0+ processor.<br>Flash 256KB, RAM 32K<br><br><a targe
