Wireless I/O


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 costly 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-LP24 features

  • License-free 2.4 GHz
  • Designed for global use
  • For short-range, clear line-of-sight applications up to 5 kilometers
  • Easy, software-free configuration
  • FHSS (Frequency Hopping Spread Spectrum)
  • License-free ISM (Industrial, Scientific and Medical) band
  • Up to 32 I/O modules can be attached to a single radio module via T-BUS
  • Mesh networks of up to 250 devices
  • DIN rail mountable
  • IECEx Certificate, can be used in potentially explosive environments

For simple I/O and serial communications

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 up to 250 nodes. 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-LP24 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.
