S257 Cellular Smart Meter Electricity Power Rtu Iot Gateway - China

The Cellular Electricity Power IoT RTU is a powerful smart meter used for power internet of things solution, is special using for remote monitoring 100~400VAC of 3-Phase electricity power distribution safety and measurement, can measuring the 3-phase 3-wire, 3-phase 4-wire distribution power voltage, current, factor, watts, frequency, apparent power, active power, reactive power, active energy, reactive energy.

Also, it provides Dual SIM, 2 digital inputs, 2 relay outputs, 1 ambient sensor input for monitoring onsite temperature and humidity, also 1 RS485 for extend I/O to monitoring oil level and temperature or read meters.

1 - Can be operated from anywhere, no distance limitation; 2 - Quad band 850/900/1800/1900Mhz GSM GPRS Module inside.

3 - 3G/4G/NB-IoT Modules are optional, LCD Display is optional; 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 anti-jamming and in-built watchdog; 6 - High isolate voltage, current and voltage input signal isolated by accuracy transformer, afford arrive DC2500V; 7 - Working Voltage: 60~500VAC or 70~800VDC; 8 - 3-phase 3 wires or 4 wires power parameter measurement, include voltage, current, factor, watts, frequency, apparent power, active power, reactive power, active energy, reactive energy, phase loss; 9 - Measurement range: AC100~400VAC, currant range: 5A, other range should use CT; 10 - 2 digital inputs, compatibles dry and wet contact, 2 relay output (5A/30VDC, 5A/250VAC), compatibles pulse outputs; 11 - 1 ambient sensor input for monitoring onsite temperature and humidity ; 12 - 1 RS485 port, supports Modbus RTU Master and Slave, can be used to extend I/O ports or meters; 13 - Provides 1 channel DC power source output for external device, saving wiring cost; 14 - Each parameter can setup threshold, when exceed or recovery will alarm immediately; 15 - Can monitoring phase loss, when occurs will alarm immediately.

16 - Inbuilt inter-lock logic programmer and powerful timer program function.

17 - Resend the data while communication failure and alert to users by SMS; 18 - Inbuilt TCP/IP protocol stack, supports cloud, APP and web server applications; 19 - Supports Modbus TCP, Modbus RTU protocol and transparent transmission, can be used as master and slaves, can integrate to SCADA, HMI, DSC directly; 20 - Supports USB setting, reading, records inquiry and firmware upgrade; 21 - Supports 100000 historical records for checking; 22 - Integrated 1 Industrial 10/100M adaptive Ethernet module inside, supports Modbus TCP; 23 - Supports SMS Alert when overload, I/O triggered or recovery, and external power lost or recovery; 24 - Up to 10 SMS Alert and dial numbers, can program to receive specified alarm message; 25 - Inbuilt large capacity automatically rechargeable backup battery; 26 - Industrial class design suitable for long time work applications; 27 - Using metal shell, protection class IP67 - Metal shell and system security isolation, especially suitable for industrial applications in the field; 28 - L250 * W220 * H70mm, weatherproof metal enclosure.
