Ray 3 with Modbus (RS485) + M-Bus +3G + 4 x Discrete IN + battery backup + SD card slot

About the product

RAY-3 data logger is dedicated for measuring of analog (voltage, current, resistance) parameters, for tracking the status of discrete inputs, formation of discrete output signals, archiving and sending data to local users/server over RS232/RS485 or USB and to remote users/server over Ethernet or/and GSM/GPRS/EDGE or UMTS/HSPA+ using Modbus TCP/IP protocol.

Technical Features

 - Possibility to choose interfaces: M-Bus, RS232, RS485, USB, GSM/GPRS, Ethernet, Analog IN/OUT, Discrete IN/OUT
 - Supported protocols: Modbus RTU, Modbus TCP/IP, M-Bus, IP, ICMP, UDP, TCP, DHCP, PPP, ARP, SNTP, IEC60870-5-104:200 DynDNS, FTP server, FTP client, DNS client and transparent
 - Independent data log with real time stamp (Real Time Clock)
 - Alarm limits tracing of analog and discrete inputs, logging in event archive, warning about alarms over GSM/GPRS/EDGE or UMTS/HSPA+, Ethernet and by sending SMS
 - Reading data from M-bus meters (heat, water, gas, electricity...) via M-Bus interface
 - Alarms status of analog and discrete channels fixing
 - Data from local device reading over RS232/RS485 (using Modbus RTU protocol) or USB 
 - Remote communication over Ethernet or GPRS/GSM / 3G
 - Up to 6 analog inputs (voltage, current, resistance, PT100)
 - Up to 2 analog outputs
 - Up to 4 discrete inputs (contact / impulse / alarm)
 - Up to 2 discrete relay outputs
 - Galvanically isolated interfaces and power supply
  - Additional special transparent protocol data transfer
 - Internal battery ensure at least 1 hour operation, after power fail

Application possibilities

Advanced Data Logger / Control unit RAY-3 is dedicated for real time logging and analyzing different kinds of discrete signals and controlling other devices via Discrete Outputs or Modbus. Using GPRS / 3G or Ethernet, logger sends data to remote users / server. RAY-3 can also communicate with other controllers and sensors. Device has wide range of optional interfaces and protocols. Perfect for industrial control, telemetry/monitoring, control and smart metering.
