4G SMS Remote Terminal Unit S475 for Fire Panel Monitoring

T RTU 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.

The Cellular IoT Modbus RTU S475/S475E inbuilt TCP/IP protocol stack make it suitable for internet of things (IoT) applications, it can be operated easily by the provided cloud, app, and web server, or integrated to your IoT

applications via Ethernet or the TCP/UDP protocol, or integrated to SCADA systems by standard Modbus TCP protocol, too. This is very useful if you need remote control onsite devices with low cost solution.

The Cellular IoT Modbus RTU S475/S475E supports 2 RS485 ports,which can be used as Modbus RTU Master and Slave at the same time and supports transparent data transmission . The Cellular IoT Modbus RTU can be used as Modbus RTU Master to reading smart meters, I/O modules, PLC, and converts to SMS alert once triggered the threshold value, or transmit data to remote server over GPRS/3G/4Gnetwork.
