Overview

KRL 70 is a licence-free transmission system (Radioline) for remote transfer of data in infrastructure applications. The solution offers wireless signal transmission of measuring values for flow, level, pressure, temperature, analytical and other devices via an external power-operated license-free radio modem. It transmits serial data (Modbus RTU), digital and analogue signals (0/4…20 mA) as well as digital pulses. The transmission range of the radio system is up to 20 km / 12 mi from one station to another. The range can be extended by the use of intervening stations as each station amplifies the signal to the control panel as a repeater.

  • For large networks (of up to 250 stations) and distances (of up to 20 km / 12.4 mi point-to-point)
  • Enables various network structures: from a simple point-to-point connection to complex networks
  • Universal use:
    • I/O-to-I/O
    • I/O & Modbus RTU to Modbus RTU PLCs
    • I/O integration in Modbus RTU PLCs
    • Serial cable replacement RS 232/485
  • Can be extended with up to 32 I/O modules
  • Easy module replacement even during operation (hot swap)
  • License-free 868 MHz (900 MHz USA) frequency band
  • Configurable data rates of data transmission interface
  • Easy startup of wireless systems – by simply turning the thumbwheel, without any programming
  • Hazrdous area approvals
