MIOS system is a special design isolated signal remote I/O system, it linked a local area network designed to connect controllers to remote I/O chassis and replacement of discrete wirings by fieldbus or industrial Ethernet communication. MIOS supports up to 31 slots with as many as 128 I/O points in each system. If you need more, you can expand your system with Ethernet router, easily support thousands of I/O points in a single system Power Supply 24VDC�±10% MWG1 â?¦ 1W, other module â?¦ 3W Analog input Max 60 channels Digital input Max 60 channels Analog output Max 60 channels Digital input Max 60 channels Communication (RJ45 port) 10m/100m Protocol Modbus TCP, TCP/IP, http Modbus TCP(client) Max 6 connections http (client) Max 2 connections Communication (Modbus Port) Protocol Modbus RTU Address ID range 1~254 Insulation Resistor >100M�© / 500V between the input / output Isolation Strength AC1500v 1min between the input / output Ambient Temp. / Humi. -40 ~ 85 C / â?¦95% RH Dimensions 113 X 109 X N mm (N â?¦17.5*32) Terminal Wiring Screw mounting, AWG #26-12 Comm Interface Mini USB Standard EN61326-2003 LED Indicator Normally lighting indicates power supplied and working normally, blinking indicates digital communication is under way.
