The Cellular IoT Gateway S475/S475E is an industrial class, high reliability, high stability, and programmable Remote
Terminal Unit (RTU). It embedded 32-Bit High Performance Microprocessor MCU, inbuilt industrial Cellular
module. It provides 8 digital inputs, 6 analog (ultra high 24 bit resolution) or PT100 Resistance Temperature
Detector (RTD) inputs, 4 relay outputs, 1 ambient sensor input for monitoring onsitetemperature and humidity,
1 Ethernet RJ45 port for connect internet WAN or LAN, and 2 RS485 serial port,supports 320 IO tags via Modbus
RTU protocol. It can monitoring and operates the I/O ports by SMS, APP, Web Server, internet, timers and
programmed inter-lock events automatically
