The SATEL-LP product family is designed for simple I/O and serial communications. With software-free radio setup, SATEL-LP provides a cost-effective wireless solution where it is too expensive or impossible to run a wire. All SATEL-LP modules are DIN rail mountable. The communications over the air interface is secured with a 128-bit AES encryption and authentication.


SATEL-LP8 features

  • Licence-free 869 MHz
  • Designed to be used in Europe
  • For short- or middle-range applications of up to 20 kilometers
  • Easy, software-free configuration
  • Up to 32 I/O modules can be attached to a single radio module via T-BUS
  • FHSS (Frequency Hopping Spread Spectrum) (Depends on the topology and baud rate)
  • Mesh networks of up to 99 devices
  • IECEx Certificate, can be used in potentially explosive environments


For serial and I/O data transfer

The system consists of data transfer and expansion modules. The data transceiver modules are used for serial data transfer and expansion modules for I/O signals. I/O signals can also be connected directly to Modbus protocol devices with transceiver modules through RS-232 and RS-485 interfaces.

With SATEL-LP system it is easy and simple to create point-to-point, point-to-multipoint or large mesh networks. The commissioning can be done without any programming via the thumb wheel – a wireless connection is established automatically. Through AES encryption, frequency hopping spread spectrum, and coexistence management the system reliability is extremely high and data transfer is secured 24/7.


IECEx Certificate

SATEL-LP 8 has an IECEx Certificate, which means that it can be used in potentially explosive environments. IECEx is very similar to European ATEX system; both use the same standards (e.g. EN-IEC 60079-0). Products with IECEx Certificate are accepted in several countries globally.
