DATA CONVERSION

1. 0 - 100% DATA CONVERSION (R7HL-SV4, R7HL-SVF4, R7HL-YV2, R7HL-YS2)

Analog input data is converted into digital representations of 0 – 100% proportional to each scaled range. The converted %

values are multiplied by 100 and expressed in 16 bits.

Overrange input is possible from -15 to +115% of the nominal range. When the signal exceeds the limit, the data is fixed at

-15% or +115% respectively. Negative value is represented in 2’s complements.

Converted Data, Hex

Analog output is converted in the reverse order of the input data. The output range 0 – 5 V DC is expressed as 10000 at

5.0 V (100%) and 0 at 0 V (0%).

2. 12 BITS DATA CONVERSION (R7HL-SVF8NL, R7HL-YV4L)

The analog data for input is converted to 12 bits digital value (0 to 4095) by each input range.

Input range refers range of the input, when input exceeds this range it is fixed to 0 or 4095.

For analog output, it is converted in reverse of input.

When output range is 0 to 5 V DC, output is 5.0 V (100%) for ‘4095’, 0 V (0%) for ‘0’.

3. ENGINEERING UNIT CONVERSION (R7HL-TS4, R7HL-RS4)

Engineering unit value °C or K is multiplied by 10 and expressed in 16 bits. °F data is represented in engineering unit

value, without multiplication. Negative value is represented in 2’s complements.
