5111 is GSM/GPRS Remote Terminal Unit for remote monitoring and controlling or alarm to mobile phones. General features:

CWT5111 GPRS RTU enables various kinds of devices with I/O and AD and Standard 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. CWT5111 is an ideal solution for factory automation, environmental monitoring and remote device management for M2M industry.

8DI + 8DO + 4AI + GPRS transmission + sms alarm

Key features: 

Advance features

Adopted highly integrated industrial CPUReliable performance with built-in double watchdogLow maintenance, 24×7 operationAudio in and audio out can connect speak and micTemperature sensor (optional)Internal battery and providing power cut off alarmEasy used GUI configure software

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.Every AD input current values can be query via commandConfigurable for the SMS alarm and recover messageConfigurable for alarm ensure timeConfigurable for alarm delay timeConfigurable for offset and gain

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 or CWT_IO protocol
