VD-C80 Range of safety processors are a versatile platform for interfacing safety devices to automation control panels for motorised physical security. These processors are for mounting inside a control box. Power is supplied by the control panel. There are 2 volt free outputs.
VD-C82 two 8k2 resistive inputs with control options.
8K2 Resistance measuring inputs provide a simple fail safe standard for safety edges . Conductive rubber edges are by na-ture, normally open. An 8k2 termination resistor in the far end presents processors with the 8K2 resistor value. When pressed, the resistance drops to under 100 ohms. The safe range is from 6K8 to 10K ohms, centred on 8K2.
