The radio controlled safety module UH 6900 in group mode is an innovative wireless safety system to protect man and machine. A feature of the wireless safety system is its safety-oriented uni-directional radio transmission for transmitting signals between one wireless safety module as group control device and one ore more group receivers so that the two separate safety devices, each of them installed on a different machine part that is not connected to the other by wires (for example, moving machine parts), work together as one system.

Therefore SAFEMASTER W radio controlled safety modules are intended for the wireless remote control of machines and plant parts that used to be controlled by cable. Their usage is only restricted by valid safety instructions that prohibit, for example, staying under suspended loads.

The radio controlled safety module UH 6900 group controller always works together with one or more UH 6900 group receivers actuating their safety related output contacts via an uni-directional radio connection. The local output contacts of the group controller must not be used as safety contacts. They are only used for monitoring purposes.

Typical applications are:
• Hazard areas where protective equipment is necessary for the safety of persons but where wiring is impossible or not reasonable, for example in applications with extremely wide-spread, extensive hazard zones;
• Mobile and stationary plants and equipment, for example large machines, assembly halls and scaffolds, conveyor belts, high-rack warehouses, warehouses, forklifts, etc.
• The radio transmission range is up to 800 m

Features

  • For Applications- Performance Level (PL) e and category 4 to EN ISO 13849-1- Maximum SIL 3 according to IEC/EN 62061:2021- Safety Integrity Level (SIL) 3 to IEC/EN 61508 and IEC/EN 61511
  • Machine directive 2006/42/EG
  • EN ISO 13851: Safety of machinery – Two-hand control devices –
  • DIN EN 300 220: Electromagnetic compatibility and Radio spectrum Matters (ERM) – Short Range Devices (SRD) – Radio equipment to be used in the 25 MHz to 1000 MHz frequency range with power levels ranging up to 500 mW
  • Depending on the operating mode, to connect:- E-stop push-button (2-channel), safety gate, LC (non-contact safety system, for example light curtain) of the type 4 in accordance with EN 61 496 or the two-hand type IIIA in accordance with EN ISO 13851.- 1 start button- Changeover switch (2-channel) to indicate radio use in the Safety operation with optional radio control operating mode
  • For two-way communication via radio:- Safety shut-down commands- Signals from 8 non-safety-relevant DC 24 V inputs at 8 non-safetyrelevant DC 24 V semiconductor outputs
  • Broken wire and short circuit monitoring function with error indication
  • Semiconductor output to indicate poor or missing radio control
  • 2 semiconductor outputs for status indication
  • LEDs to indicate- status of module- status of all inputs and outputs- the radio transmission and its quality
  • Width: 45 mm
