The Elpro 505U-K wireless I/O module is an economical solution for the remote monitoring of process signals. The 505U-K connects to discrete, pulse or analogue signals from process transducers, and transmits these signal values by radio. The 505U-K is suitable for alarm or metering applications, as well as general plant monitoring.

The 505U-K has an internal 869MHz radio transmitter which operates on a license-free radio band in Europe. The 505U-K has an operating range of up to 5km. It is suitable for monitoring in utility industries such as electricity, water and gas; and is also a cost effective solution for short range applications in factories and plants.

Mode of Operation The 505U-K is compatible with the 105U/869 range of wireless I/O products - 105U units may be used to output the process signals, or act as a wireless interface connected to a PLC, DCS or PC. The 505U-K transmits the value of its input signals whenever the signal changes, or after a pre-configured update time. Each transmission message includes error-checking to confirm the validity of the message. The 505U-K can be configured to repeat the transmission several times to ensure that the transmission is received correctly. More than 10 000 505U-K units may operate together in a single system.

Because of its battery power supply and weatherproof case, the final installed cost of the 505U-K radio telemetry module is very low, making it a cost effective solution for even simple plant monitoring applications.

  • Multiple power supply options including battery-only supply with ultra low power consumption (reverts to 'sleep mode')
  • Input only transmitter unit (2 or 4 DI/PI, 1 AI) able to be connected to multi I/O and/or gateway units - up to 3000 units in a system
  • Peer-to-peer communications with exception-reporting, reliable self-checking via update time and secure data encryption
  • External inputs plus internally calculated values including analog setpoint status, pulse rate and pulse total, power/battery supply voltage, power supply alarm
  • Can connect to up/down counter transducers such as shaft-encoders
  • Configurable repeat transmissions to five times for message reliability
