Remote Controls, Safety Relays, Gsm Remote Control
Name: GSM 3G M2M RTU (8DI+6AI+4DO+1TH+1USB+1RS232/485+RJ45+64Registers)
The GPRS 3G BTS RTU is a multi I/O port remote terminal unit, through the RS232/485 port can extend up to 64 additional I/O or connect intelligent meters or PLC. It is special for BTS monitoring, remote data acquisition, telemetrically, BTS access control and other applications. It supports voice communication, SMS, GPRS, 3G and RJ45 LAN IP communications.
The GPRS 3G BTS RTU can be used as remote access control,The authorized users can open the gate or turn on the machine with a free charge call at specified time.
The GPRS 3G BTS RTU supports Modbus RTU, Modbus TCP, TCP/IP protocol, transparent data transmission over GPRS/3G, RS232,RS485, RJ45, performs as Modbus Master or Modbus Slave.
The GPRS 3G BTS RTU can be used as Modbus RTU SMS Alarm, when the data acquisition from via RS232/485 exceeds threshold, it also can send pre-definition SMS to users.
