Cellular M2M IoT RTU (4DIN, 4Relay, 1TH, USB, RS485)

The remote monitoring module is designed for remote measurement and control system and remote data acquisition telemetry systems, such as smoke, liquid, water, flow, flood, electricity, power, energy remote monitoring and remote control. 



Key Features

• 4G network communication, can be operated from anywhere, no distance limitation;
• Wide range power supply 9~36VDC with over voltage and phase-reversal protection;
• Embedded ARM Cortex-M4 32 Bit RISC CoreRTOS system, reliable performance with in-built watchdog;
• 4 digital inputs, supports both dry contact and wet contact. Logic level: 10~30V or short circuit treated as close, 0~3V or open circuits treated as open. DIN0 as a high-speed pulse counter, sampling frequency: 1MHz; DIN1~3 as low-speed pulse counter, anti-shake time can be set 1~2000ms, default 1ms;DIN1 with arm and disarm function;
• 4 relay output (5A@30VDC, 5A@250VAC), can auto control by timer, alarm-link and remote control by SMS, cloud. The first DO can set time to control by authorize number;
• 1 temperature & humidity sensor input for monitoring onsite environment, the sensor model is AM2301, temperatures range from -40°C to 80°C, with a 0.5°C accuracy, humidity range from 0 to 100RH%, with a 3% accuracy;
• Inbuilt 32G SD card to save up to tens of thousands historical data and events;
• 1 RS485 port, support Modbus slave protocol, can link up to SCADA, HMI, DSC, PLC. Support Modbus Master protocol, can connect to 16 Modbus Salve, e.g.: Data Acquisition Module, meters, generator, PLC, VFD, etc., and 320 tags can set alarm value and content, also support data transparent transmission;
• Powerful SMS function: Threshold high SMS alert, SMS set, SMS inquiry, SMS command for Modbus PLC, and SMS monitoring communication with Slaves;
• Inbuilt 1DC output for external transducers to save wiring cost;
• Automatically resend the data while communication interrupt or failure, and failure will alert by SMS;
• Supports remote restart, remote configureand operate by SMS commands;
• 10 SMS Alert and auto dial numbers for receiving alarm message, can program to receive specified alarm message. The authorized numbers also can dial to open the door or turn on/off machine with a free charge call at the specified time;
• Inbuilt inter-lock logic programmer and powerful timer program function;
• Support SMS, dial, 4G network for alert, USB port for configuration and upgrade firmware;
• Support TCP/UDP, MQTT, Modbus TCP, Modbus RTU over TCP, BLIIoT IoT RTU protocol and data transparent transmission;
• Metal case with IP30 protection grade, safely isolated from inner system, especially suitable for industrial control application.
• Small size: 108mmx82mmx40mm, support wall-mounting and DIN Rail mounting.
