Specifications
Data Acquisition Modules, PLC Data Via RS485 Serial Port to 433 MHz Wireless Network S280
Name:Wireless GSM 3G RTUModel:S280
the Wireless GSM 3G RTU(Remote Terminal Unit) S280 is a cost effective remote terminal unit. It inbuilt quad band GSM/GPRS module (or WCDMA/CDMA2000), ISM Band 433Mhz Radio Frequency module, andARMCortex 32 Bit RISC Core. It is a multi Isolation I/O port remote terminal unit and wireless data system.
the Wireless GSM 3G RTU can be used as:
- A Wireless Data Acquisition System. Supports monitoring up to 50 wireless data acquisition module
- for maximum 400 endpoints by 433Mhz wireless network, the range covers about 2~5Km, plus WT-02 Wireless repeaters can increase the wireless distance. Each endpoint can be setup threshold value or alarm conditions, once the value exceed threshold value or activated will send out SMS to alert the
Users immediately. - A WirelessGateway. Though the WT-01 wireless data transfer unit, it can convert the meters, transducers, Data Acquisition modules, PLC data via RS485 serial port to 433 MHz wireless network and then transmits it to GSM/SMS/GPRS/3G/Ethernet network. It performs as a wired - wireless - SMS/GPRS/ 3G/Ethernet/RS232/RS485 gateway.
- A SMS Alarm Controller. the IO activations or deactivations can be reported by SMS and optionally confirmed by phone calls. Each input can have its own message texts and the message can be programmed by users.
- A Switch with SMS Remote Control. SMS texts for switching particular terminals on/off or pulse output are configurable.
- A Timer-Switch which can be Activated Automatically. It can be setup when to performs preset logic events, e.g.: timer reports its status, timer switch on/off device or equipments automatically.
- A SMS reporter. the WIRELESS GSM 3G RTU can setup daily automatically report one or more times of its current status to users automatically.
- A Data Logger. the unit can save all of the events or acquisition data in internal memory storage, the historical data can export to CS format via USB port or upload to server by GPRS /3G network according to schedule, no distance limitation.
Mainly Features:
- Inbuilt ARM Cortex-M4 32 Bit RISC Core MCU;

- Large internal memory to save up to 3500 historical records, USB port for configuration, upgrade firmware and export records;
- Inbuilt industrial ISM Band 433Mhz Radio Frequency Half duplex communication module, distance up to 2~5Km;
- Supports maximum 50 wireless Data Acquisition Modules, will alert users by SMS once the wireless DAM connect failure to ensure the monitoring working properly;
- Supports maximum 400 wireless distributed I/O endpoints;
- 2 solid relay outputs, rated capacity is 5A/30VDC,5A/250VAC;
- 4 digital inputs, compatible to dry contact or wet contact inputs. Logic level: 0~0. 5V or short circuit treated as close, +3~30V or open circuits treated as open;
- 1 temperature & humidity sensor input for monitoring onsite environment, the sensor model is AM2301, Measures temperatures from -40-80C,0.5C accuracy, Relative Humidity from 0-99RH%, accuracy is 3%;
- 1 RS485 serial port (Optional: RS232) for Modbus RTU Slave to SCADA or data transparenrt;.
