ADLINK ND-6024 - Manual (Page 60)

54 • Data Format
4.4 Hexdecimal Format
The data is in hexdecimal format as the bit 1 and 0 are set as ‘10’. The data
string length is 3 characters. It is equivilant to 12 binary bits. Because the
output of ND-6021 is unipolar, the maximum value of the digits is FFF(H) and
the minimum value of the digits is 000(H).
As the output range is set to 0~20mA, the value ‘FFF(H)’ represents 20mA and
‘000(H)’ represents 0mA. Similarily, as the output range is set to 4~20mA, the
value ‘FFF(H)’ represents 20mA and ‘000(H)’ represents 4mA.
Example 4.3.1 :
• If the output range is set as 0 to 20 mA
• The desired analog output current is 10 mA
