Sentry RS232/4-20mA PCB

Diagram

The SentryRS232 PCB provides a reliable, low cost solution for a wide range of wireless monitoring and alarm applications.

A wireless receiver, the PCB has serial, digital and 4 to 20mA outputs. It may be programmed to perform actions using the digital outputs (relays) upon certain conditions in the received data. Already successfully integrated into client applications, the SentryRS232 offers a costeffective solution for: fuel distributors, fuel storage, data logging and instrumentation, sensor and
meter companies etc.

Through our in-house application engineering and web hosting services, we can develop custom telemetry and data management solutions.

FAQ

  • What is the maximum range?
    Unobstructed line of sight is up to 1000 meters. In practice this will be reduced by walls and trees etc.
  • How is it mounted?
    There are 4 M3 pillars for mounting
  • Where is the antenna?
    The PCB has a BNC connector to allow a wide variety of aerials to be used. The application influences the choice.
  • Is it easy to use and configure?
    Yes, and it is usually shipped preconfigured
