SNR-ERD-4s-GSM
The multifunctional SNR-ERD-4-GSM controller is designed to organize an automated production process control system, including for measuring, collecting and storing data from primary converters and microprocessor measuring converters, providing the function of locking various interfaces and communication networks, registering discrete equipment status signals, issuing remote control commands, processing received information and transmitting it to higher levels of the management system.
SNR-ERD-4s-GSM controller, with the function of an Eth-RS485/RS232 interface converter, is designed for remote monitoring and control of cabinets with equipment. The survey of sensors connected to it, and load management, is carried out via SNMP and WEB, GPRS, GSM (SMS). Advanced load management capabilities. Climate control functions using air conditioners, heaters, ventilation valves.
