is used, the resistance of
the cable connecting the receiving instrument and the converter must satisfy the following
conditions considering voltage drop:
①
Low level of pulse output must satisfy the input condition of the receiving instrument:
Low level of pulse output = (If+2Ip+Is) R+0.5
②
Voltage between POWER and COMMON of the converter is within the rated voltage:
Converter voltage (between POWER and COMMON) = V−(2If+Ip+Is) R
