The Safety-Light-Barrier-Amplifier ISL-8000, in conjunction with optical safety-transmitters IST-... and safety-receivers ISR-..., yields a contactless protective device (BWS) according to the standard EN61496. Every couple of sensors consisting of an optical safety-transmitter IST-... and an optical safety-receiver ISR-... forms a powerful light barrier whereby up to eight independent light barrier routes may be realized without mutual interference. The amplifier evaluates each single light-barrier route and reports the status, interrupted or clear, via one of the eight outputs to the superior control system. The integrity of the connection to the control system may be evaluated by using internal or external testing. To reduce service effort and to equalize changing environmental conditions (e.g. sensor contamination), the transmit-power of every individual channel is constantly adjusted by the automatic power regulation.

The safety light barrier ISL, together with the sensors IST… and ISR…, is an optoelectronic protective device which is categorized as a type 2 device according to the safety standard EN61496.

Each pair of sensors consists of one transmitter IST… and one receiver ISR… The individual pairs operate as through-beam sensors and have a very small design. One great advantage of the sensors is that they may, due to their small design, be mounted anywhere.

The patented automatic operation guarantees a constant switching sensitivity. It even stays constant in outdoor areas exposed to rain and fog or heavily polluted industrial environments. The system may be used wherever traditional light curtains and grids cannot, due to their design.

Each channel has its own switching output so that it is possible to detect which channel is interrupted. The operation is controlled by a menu navigation that is shown on the LCD display.
