Model:S256
Name: Cellular 5-CH DC Electric Measuring RTU
The Cellular (GSM/GPRS/3G/4G/NB-IoT) DC Electric Measuring RTU is special designed for remote monitoring 5- channel DC electricity power. Measure each channel voltage, current, active power, active energy. When overload or exceed the pre-set value, then it will alert by SMS, Voice call, Cloud, APP, Wechat, Web Server, SCADA, HMI, DSC immediately.
The Cellular DC Electric Measuring RTU is an industrial class, high reliability, high stability, and programmable Remote Terminal Unit (RTU). It embedded 32-Bit High Performance Microprocessor MCU, integrated special measurement chip and inbuilt industrial Cellular module. It provides 4 digital inputs, 2 relay outputs, 1 ambient sensor input for monitoring onsite temperature and humidity.

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 12~36VDC with over voltage and phase-reversal protection;
7. Measurement range: voltage: 60V, 100V, 260V, 450V, 500V, current 5A, 20A, 50A.
8. Supports 5-Channel DC power: current, voltage, active power, active energy;
9. 4 digital inputs, compatibles dry and wet contact;
10. 2 relay output (5A/30VDC, 5A/250VAC), compatibles pulse outputs;
11. 1 ambient sensor input for monitoring onsite temperature and humidity;
12. Supports phase loss, phase recovery, voltage overload, current overload detection and alarm;
13. Inbuilt inter-lock logic programmer and powerful timer program function;
14. Resend the data while communication failure and alert to users by SMS;
15. Inbuilt TCP/IP protocol stack, supports cloud, APP and web server applications.
16. Supports Modbus TCP protocol, can integrate to SCADA, HMI, DSC directly.
17. Integrated 1 Industrial 10/100M adaptive Ethernet module inside, supports Modbus TCP;
18. Supports SMS Alert when overload, I/O triggered or recovery, and external power lost or recovery;
19. Provides 1 channel 12~36VDC power source output for external device, saving wiring cost;
20. Up to 10 SMS Alert and dial numbers, can program to receive specified alarm message.
