The ideal Remoted Monitoring Solution for monitoring oil and gas production and transportation assets.

With its support for a wide range of wireless communications options and high I/O count, the RMS1500 delivers unparalleled value, performance, and reliability. The Iridium option, which uses a constellation of over 60 low earth orbit satellites, allows it to communicate in areas where cellular is not available and where the ground cover and terrain prove difficult for other satellite technologies. The base product provides 4 digital inputs, 1 digital output & 4 analog inputs, An optional I/O module is available with support for an additional 20 I/O points.

Features & Benefits

  • Class 1 Division 2, Groups A, B, C, D certified terminal meets industry standards for electronic equipment in Oil and Gas markets.
  • Modbus protocol interfaces directly with common SCADA devices such as RTU, PLC and flow meters to quickly and easily implement reporting and telemetry capabilities for remote equipment.
  • RS485 serial interface allows connection to SCADA devices over large distances to enable flexible deployment in a wide range of operating conditions.
  • Seamless global coverage based on the Iridium satellite constellation enables operational benefits in remote regions.
  • GSM and CDMA cellular modems also supported.
  • Expanded operating temperature range allows reliable deployment in some of the world’s most demanding environments.
  • Immediate reporting of digital status change (all data sent with report).
  • Over-the-air programming enables M2M to remotely reconfigure parameters such as threshold levels or report frequency.
