Description for BECKHOFF KL2692 Cycle Monitoring Terminal (watchdog)
The KL2692 Bus Terminal monitors a bit that is toggled by the controller during each cycle. If the toggle signal fails, the controller switches off two potential-free relay circuits in order to prevent damage to the machine. Failure of the toggle signal may be caused by the PLC cycle stopping, by a fault in the bus cable or connector, or by a fault in a bus device. The cycle monitoring time can be parameterised. The Bus Terminal has an enable input that enables the relay to be switched on if a correct toggle signal is detected.Technical dataKL2692 | KS2692Connection technology2-wireNumber of outputs2 potential-free relay outputs (normally-open contacts)Number of inputs2 digital 24 V inputsRated load voltage30 V DCMax. output current3 A per channelOhmic switching current5 A AC/DC per channelInductive switching current2 A AC/DC per channelMinimum permitted load10 mA at 5 V DCElectrical isolation500 V (K-bus/field potential)Current consumption power contacts–Current consumption K-bustyp. 165 mABit width in the process image2 x 8 bit data, 1 x 8 bit control/dataOperating cycles mech.
