Application Notes

EAP-032059

In order to supply power to two-wire transmitter, we are planning to use your Current Loop Supply model DS-24-_.

The Output 1 will be provided to a recorder, and the Output 2 to a computer. As far as I looked over its specification sheet, I could not find any description of load resistance for each output. Could you tell me these values?

Model DS-24 is a unit to supply a power to two-wire transmitter. As shown in the Figure, the 4-20 mAdc from two-wire transmitter is transmitted to the output terminal of the DS-24 as it is.

In short, the value of load resistance is up to the specification of two-wire transmitter. In case the Output 2 is utilized, after you look over the load resistance of two-wire transmitter, make sure that the total load resistance at the Output 1 and the Output 2 is within the value of load resistance.
