Brief Introduction
The GSM 3G M2M RTU(Remote Terminal Unit) S272 inbuilt quad band GSM/GPRS module (Or 3G UMTS/HSDPA) and ARM® Cortex™ 32 Bit RISC Core. It is a multi Isolation I/O port remote terminal unit. It is special for remote control and remote data acquisition, Base Transceiver Stations monitoring, access control,ATM, generator monitoring, Pump station monitoring, weather satiation monitoring and other applications.

The S272 GSM 3G M2M RTU is designed as a cost effective remote control system alert device. It monitors up to 8 digital inputs and 4 solid relay outputs and 6 AD inputs and power status, onsite temperature and humidity.

All of the inputs and outputs are isolation. User-defined SMS is sent to pre-configure mobile phone numbers when a pre-defined alarm condition happens. These pre-configured mobile phone numbers can belong to technicians or engineers who are responsible in handling corresponding alarms. With the aid of this GSM 3G M2M RTU, the alarm condition brings attention to in-charge personnel immediately. Besides it allows those mobile phone users to trigger any relay output by using SMS. The output can be connected with alarm indication device, such as alarm, and others. Moreover, the GSM 3G M2M RTU can be used as a smart PLC(Programmable Logical Controller) by the
interlock function. And be used as a remote access control, the authorized users can open the gate or turn onthe machine with a free charge call at specified time.

The GSM 3G M2M RTU supports Modbus TCP, TCP/UDP protocol, data transparent transmission via RS232 /RS485 ports over GPRS/3G network.

GSM 3G M2M RTU can be used as:
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.

An Access Control unit. Up to 10 authorized tel. numbers can be authorized for dial to access control and open the electricity door directly with free charge.

A PLC Automation Control system. Upton 40 programmable logic events can be preset by users. E.g.:Each input alarm or recovery can link to one or more output actions, this is very useful when the temperature up to appointed value, need switch on the air-conditioning immediately, or when water overflow and need switch on the dryer, or when somebody broken into the door or windows need to start the CCTV and Siren.

A SMS reporter. The GSM 3G M2M RTU can setup daily automatically report one or more times of its current status to users automatically.

A Pulse Counter. The digital inputs can be used as the pulse counter, the user can setup both of interval value activated alarm and total value activated alarm.

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.

A Wireless Data Acquisition to SCADA or HMI or Monitoring Center. The unit can acquisition variety data(E.g.: Pressure, Level, Current, Voltage, digital input status, pulse counter, digital relay output status, temperature value, humidity value and other) and upload to the SCADA(supervisory control and data acquisition) or HMI or Monitoring Center by SMS/GPRS/3G, no distance limitation.

A GPRS/3G DTU. The Unit can be used as GPRS/3G Data transfer unit for data transparent transmission. Plus the I/O port, so it can be used as data transfer unit and SMS Alarm Controller.
