Note: This 3G alarm unit is only suitable to use in America Continent.
The GSM 3G M2M RTU (Remote Terminal Unit) is a multi Isolation I/O port remote terminal unit , supporting 3G CDMA2000 and quad band GSM/GPRS module, which is specially 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 GSM 3G M2M RTU is designed as a cost effective remote control system alert device. It monitors up to 4 digital inputs and 4 solid relay outputs and 4 analog 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 on the machine with a free charge call at specified time.
The GSM 3G M2M RTU supports Modbus TCP, TCP/UDP protocol, transparent data transmission over GPRS/3G network.
The 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 perform preset logic events, e.g.: timer reports its status, timer switch on/off device or equipments automatically.
*An Access Control unit.
Up to 10 tel. numbers can be authorized for dial to access control and open the electricity door directly with free charge.
*A PLC Automation Control system.
Upto 10 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 upto 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.
*Built-in 3G CDMA2000 850/1900MHz and 850/1900Mhz GSM GPRS Module;
*4 analog inputs, 12bits resolution, support 0-5V, 0-20mA, 4-20mA output transducers;
*4 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. One of the inputs can be used as counter, sampling frequency is 1Khz;
*1 temperature and humidity sensor input for monitoring onsite environment, the sensor model is AM2301, Measures temperatures from -40-80°C,0.5°C accuracy, Relative Humidity from 0-99RH%, accuracy is 3%;
*Widely Rated voltage range, 9~36VDC, Inbuilt large capacity rechargeable backup battery;
*Large internal memory to save historical data, USB port for configuration and upgrade firmware;
*All of the I/O ports with electromagnetic isolation protection;
*2 IP data centers, supports Modbus TCP, TCP/IP protocol over GPRS/3G network;
*Automatically resend the data while GPRS/3G communication interrupt or failure, GPRS/3G failure will alert by SMS text to users.
*Supports remotely restart the RTU, and configure & operate it by SMS commands remotely;
*Supports over voltage protection and phase-reversal protection, provide DC power sources for external transducers or sensors to save wiring cost.
*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.
