Modbus GPRS RTU

CWT5002-2 MODBUS GPRS RTU enables various kinds of devices with I/O and AD and Standard MODBUS protocols

      CWT5002-2 MODBUS GPRS RTU enables various kinds of devices with I/O and AD and Standard MODBUS protocols to communicate over GSM/GPRS network and the Internet easily and freely. It can construct a smooth “GPRS Data Tunnel” between Host End and Remote End, ensuring an efficient communication for data transmission and remote device management. It also support send user-defined alarm sms when pre-defined alarm condition happens, and can be controlled via SMS command.

With 8 Digital Inputs, 8 drivable Outputs, 4 analog inputs and 1 selectable RS-232/485 serial port connect slave to read and writer 32 registers, CWT5002-1 is an ideal solution for factory automation, environmental monitoring and remote device management for M2M industry.

Monitor 32 registers on modbus + 8DI + 8DO + 4AI + GPRS transmission + sms alarm/control

8 digital inputs feature

Upload data when inputs are triggeredUpload input status on scheduleCan be reuse as pulse counter inputSMS alarm when inputs are triggeredNO or NC type can be presetConfigurable for alarm and recover smsRemote query inputs status

8 relay drivable outputs feature

Multiple output type can be presetRemote On/Off/Pulse outputs via GPRS or smsConfigurable for pulse timeRemote query outputs status via GPRS or smsOutputs can be activated by alarm or callOutputs can be activated on schedule

4 analog inputs feature

Can preset normal range for AD input, upload data to server when above the normal range.Current values can be query by server or smsConfigurable for alarm and recover SMSConfigurable for alarm ensure timeConfigurable for alarm delay timeSupport offset and gain

Modbus feature

Modbus RTU protocol on RS232 or RS485, monitor modbus slaveRead or write 32 registers (coil or input registers) on Modbus via GPRS or SMSUpload data to server when coils are triggeredCan preset normal range for input registers; upload data to server when above the normal rangeSupport SMS operation (read or write registers)

GPRS feature

Support connects 4 servers, the servers must connect internet and have static public IP address or Dynamic Domain nameGPRS Transmission base on TCP/IPSupport modbus TCP protocol
