digital counter Feature 1. Using SCM function, operation easy 2. Appear six digit counter, exact quantity are digits after the point(rest the point will get 10 digits counter 3. Relay output have four output models(R,N,C,F) 4. Backup data for power fail,the data will be kept 10 years after the power fail 5. Two passage output alarm with relay Model and parameter 6. Many models, suitable for various industrial equipment Counting signal Input impedance more than 100KΩ Input level H more than 5V; L less than 2V Max. input 50V Step Descend edge Relay output Output mode R,N,C,F Output cycle 0-99.99s Contact burden 250VAC/3A Power supply AC90V-260V (50Hz) Anti-interference ±3000V ±2500V Ambinet temperature 0 to +50°C Storage temperature -20°C to +70°C Withstand impedance Min100MΩ Counting speed (4 class forset) 20CPS,200CPS,3000C PS,10000CPS
