 Product Features

  • Ease of use
    Absolutely no programming or technical knowledge is required to use this system. Any computer can access its HTML web-based control panel using Internet Explorer, Mozilla Firefox, Google Chrome, etc.  

  • Intuitive user interface
    Although RTU is rich and complete in functionality and performance, configuring it to user specific requirement is a breeze.

  • Flexible User configuration
    Configurable easily with any local or remote computer. Only authorized with the correct user ID and password can access RTU.

  • Remote access
    RTU can be connected to any computer in the local area network (LAN) environment, as well as easily setup for remote access and control over the Internet.

  • Expandable
    Additional Input-Output expansion boxes, temperature monitoring, industrial controllers, even third party software can communicate with it via Modbus serial protocol.

  • Microcontroller based design
    It is not a PC hardware and does not contain moving parts like hard disk, CD-ROM drive that can affect its reliability.

  • Low power consumption
    Because it does not consume much power, RTU does not generate heat and will run for 24 hours without worries of breaking down. In the event of incoming power failure, it can operate for hours on a small capacity lead acid battery / power supply unit.

  • Small & Compact
    The dimension is just 70(l) x 38(h) x 100 (d) mm and weight a mere 480 grams, it can be fitted into any chassis or equipment cabinet or be obscurely installed in any corner of the equipment room.

  • Repeat SMS
    If enabled, when an alarm is triggered, the SMS will be sent to the operation and forward group repetitively at the interval specified during software configuration. To cancel repeat sending, any mobile phone from the operation or forward group must acknowledge to RTU by replying the acknowledge command. Once RTU received the acknowledgement command it will stop sending further SMS for this trigger.

  • Automatic Health Check (RT-1 only)
    The “Auto Health Check” message allows user to check, via SMS or enable to auto check that the RT-1 unit is functioning properly: If “enable” is checked, RT-1 will send a SMS message on scheduled system date and time. If the auto health check is not enable, user still can perform manual health check by sending a SMS health check command.

  • Remote Phone Management
    Re-assigning of operation personnel, a change of mobile phone number is also common. Rather than having to physically go to the installation site with a notebook computer, the authorized personnel can perform the change from anywhere using their mobile phone. Where there are many installed sites, distance or time is a concern, this becomes very efficient.
