Modular RTU S275

GSMGPRSRS-485

Cellular IoT Modbus RTU (8DIN,6AIN/PT100,4Relay,1TH,USB,RS485,320 mapping registers) Model no：S275 The Cellular IoT Modbus MQTT RTU supports transparent data transmission and performs as Modbus Master Slave over GPRS/3G/4G network and RS485 serial port. Moreover, 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/4G/NB-IOT network. Compatible Modbus TCP and MQTT IoT Protocols,can intergrate to the KPIIOT IoT Cloud Platform or other IoT Cloud Platforms or SCADA or OPC servers. 1. GSM GPRS 3G/4G/ Modules are optional; 2. MQTT/Modbus RTU/Modbus TCP protocol; 3. with 320 mapping registers,can convert modbus rtu to MQTT or modbus TCP; 4. Modular design, can easily upgrade the cellular module if network upgrade; 5. Embedded ARM® Cortex™-M4 32 Bit RISC Core, 168 MHz inside, RTOS system, reliable performance with in-built watchdog; 6. Wide range power supply 9~36VDC with over voltage and phase-reversal protection; 7. 8 digital inputs, compatibles dry and wet contact, DI0-DI3 can be used as pulse counter; 8. 6 analog inputs, 12bit resolution, compatibles 0/4~20mA, 0~5V, can change to PT100 Resistance Temperature Detectors; 9. 4 relay output (5A/30VDC, 5A/250VAC), compatibles pulse outputs; 10. 1 ambient sensor input for monitoring onsite temperature and humidity; 11. Inbuilt inter-lock logic programmer and powerful timer program function;
