In the temperature range – 50 °C to + 200 °C, the following formulae can be used for working to an accuracy of ± 1 % (± 1.5 °C). Repeating accuracy is significantly higher.T[° C]=DV 2.08 - (0.509 • 10-³ • DV)261,8T=temperature in ° CDV=digital value (0 … 1023)Example 1:digital value DV=562temperature T in ° C ?T[° C]=562 2.08 - (0.509 • 10-³ • 562)261,8= 51.5 °CDV=2.08 • (261.8 + T) 1 + (0.509 • 10-³ • (261.8 + T))DV=digital value (0 … 1023)T=temperature in ° CExample 2:preset temperature T = –10 °Ccorresponding digital value DV ?DV=2.08 • (261.8 - 10) 1 + (0.509 • 10-³ • (261.8 - 10))= 464Resistance measurement up to 2.5 kΩSpecial temperature sensors or any other resistances up to 2.5 kΩ can be con- nected to the PCD2.W220. The digital value can be calculated as follows:DV=4092 • R(7500 + R)where 0 ≤ DV ≤ 1023 and R=the resistance to be measured in Ω.5-66PCD2.W3x05.8.4PCD2.W3x0, analogue inputs, 8 channels, 12 bit resolutionApplication
