Product Description

The device ISG-N138 is equipped with microprocessor-based technology. It is equipped with features that normally can only be found in automatic or multiplex amplifiers. Every error caused by transmitter and receiver wiring is reported immediately by the permanent sensor-control. An included time delay offers, for example, the gating of short interruptions of a light barrier or a pulse stretching. Switch-on and switch-off delay time can be activated simultaneously. The 4-fold frequency change-over is useful to decouple nearby light barriers. Two level settings allow an adjustment to be made to compensate for distance and for different operating conditions. By the use of dark switching, it is possible to reverse the switching behavior of the output. The alarm output indicates sensor errors as well as decreased visual contact caused by contamination or misalignment. Includes a relay output for high switching loads.
