The basic RCB7000 transmission system includes a transmitter unit and a receiver unit.
These units can be used to send or receive all types of digital signal, and also analogue signals, using radio frequencies.
The radio units can communicate in unidirectional or bi-directional mode using a single frequency (technology based on a transceiver).

The transmission systems use a technology based on our extensive experience in this field (+/- 15 years), i.e. tried and tested in industrial applications such as steel works and foundries and in an environment where the electromagnetic interference may be very strong..
They operate either in the frequency band 434 MHz or 868 MHz (license-free frequency) using a low power output (less than 10mW) as standard, in order not to interfere with other radio controlled applications on the client’s site.

• Remote wireless transmission of all types of analogue measurement signal, for example weight, pressure, temperature, speeds, etc. to a central PC or automatic controller.
• Transmission of all digital or analogue signals, for example position of mobile machinery, zoning of overhead cranes or other mobile plant, remote control of machinery, pumps, motors etc., transmission of information between a mobile machine (Clark/or equivalent industrial forklift) and a fixed unit.
• Transmission of information of all types from display screens.
• Control and access authorisation management, remote barrier opening and closing, transmission of access badge information, access control.

The IRC /RCB7000 units have control systems and codes designed to ensure a high level of reliability against interference or interruptions, which could be caused by other radio frequency sources on the site, by means of the following :

• Address codes identifying the IRC receiver and transmitter (32-bit codes)
• Frame coding sent by 16-bit CRC /IRC code.
• Continuous re-reading by internal protocol and message verification.
• In the event of interference, the transmission channel can easily be re-programmed by PC on site, 64 channels are available.
• In bi-directional mode, there is also the option to check if the digital contact signals have executed properly.

• Complies with the R&TTE directive (EN 300 220, EN 301 389-1/3).
• Electrical safety EN 60950.

• 2 transmitter or receiver units in polycarbonate (or aluminium, as an option).
• IP65 waterproof housing can be installed outside or inside buildings, may also be installed in an electrical cabinet.
• 24 or 48 V AC/DC power supply (powered by batteries also possible).
• Unit supplied with fixing screws and rubber bushing.
• Omni-directional aerial fixed inside the unit, no particular installation requirements, i.e. not sensitive to the presence of a metal mass in the propagation field.
• Option to connect several transmitters and receivers together to create a network.
• Option : Receiver type RCB 7000, can be connected with Profibus, Ethernet, CAN bus or any other fieldbus connection to the PLC customer application.
