4.3.3.
Function 2. Direct BCD.
The direct BCD is only useful for 3 digits displays.
The BCD direct function permits control a display digit by digit with 14 inputs. Three
groups of 4 inputs control the value of the digits. The other two inputs control the decimal point.
The inputs power supply should be between 12V and 26V CC and the inputs can be
PNP, NPN or CONTACT.
The inputs E1-E4 control the digit 1. The one of the right.
The inputs E5-E8 control the digit 2. The one of the center.
The inputs E9-E12 control the digit 3. The one of the left.
The input E13 controls the decimal point of the digit 2. Central digit.
The input E14 controls the decimal point of the digit 3. Left digit.
The function of each input is explained in the following table.
