Availability This item is in stock and ready for immediate dispatch. FAQ What is the specific application for the ‘R=8k2’ specification?The ‘R=8k2’ indicates that this safety unit is designed to work with safety edges that have a nominal terminating resistance of 8.2 kilo-ohms. This resistance value is constantly monitored to ensure the integrity of the safety sensor circuit. Can this unit be used with non-resistive safety devices like light curtains?No, this model is a resistance evaluator and is specifically intended for use with resistive sensors like safety edges or mats. It is not compatible with OSSD (Output Signal Switching Device) outputs from light curtains or scanners. What do the ‘ready’ and ‘stop’ LEDs indicate?The ‘ready’ LED indicates that the power supply is on and the safety circuit is closed and operational. The ‘stop’ LED typically illuminates when the safety edge is activated (detects an obstacle) or if there is a fault in the sensor circuit, indicating that the safety outputs have been opened.
