DESCRIPTION

MULTIBEAM USER'S GUIDE

This interface system has been developed to be the link between a programmable controller and a 16 Microcell-type beam. This system simplifies the wiring of the beams and reduces the number of connections to the controller by using an RS485 intelligent communication. The control of the beams being entirely in the hands of the interface system, the controller is free for other duties.

SPECIAL FEATURES

￿The product is composed of two modules: one controlling the emitters, the other controlling the receivers and the communication. The decentralized connection between the emitters and the receivers simplifies the heads wiring.

￿Easy connection between the product and the controller : 4 wires are enough for the power supply and the communication ;

￿Half Duplex RS485 communication port well adapted to industrial environments ;

￿Transmission speed selection : 9600 or 19.200 bps ;

￿Possibility to choose between ASCII bus mode or quick mode ;

￿Possibility to connect up to 4 interface systems on the same communication bus ;

￿Response time of the beams without frame transfer time : < 20 ms ;

￿Detection of short-circuit on the receivers (only possible on quick mode) ;

￿Control LED on the emitting module ;

￿Status of the beams visualized by red LEDs on the receiving module ;

￿Low current consumption : <100 mA under 12 to 24 Vdc ;

￿3.5mm pitch Plug connector to make the pre-wiring and the maintenance easier ;

￿Extruded profile aluminum housing, solid and easy to install ;

￿Each beam is fit out with a plug connector to make the pre-wiring easier ;

￿Product complying with the EC norms in force ;

￿Possibility to increase the beam range up to 6 meters on request.

FUNCTIONNAL DESCRIPTION

This product has been developed to control 16 Microcell-type IR beams.

This interface is divided into 2 modules : one for the control of the 16 emitters and the other for the control of the 16 receivers.

This system must be used with a programmable controller fit out with a communication terminal. The controller supplies the 24 VDC voltage to the interface system. A 5 wires cable links the two control modules.
