Internal resistance is 4�0 / 2�0 = 2�0 Ω

Maximum wire length is 2�0 /13/km = 154 m (508 ft)

Calculation example 2: How to find the max number of sensors with a known cable length

Example of a slave CPM with 200 m of wire to sensors:

•

Current consumption of the sensor is: 20 mA max

•

Max voltage drop on the far end Sensor is 4�0 V (When using 28 V DC on the GP3496 0005)

•

Cable resistance is 13 Ω per km with the use of 1�5 mm

, (14-16AWG)

•

Wire length is 200 m with 1�5 mm

, (14-16AWG)

Total wire resistance is 0�2 * 13 Ω per km = 2�6 Ω

Max current consumption is 4�0 / 2�6 = 1�54 A

Maximum number of sensors is 1�54 / 0�020 = 77 sensors

It is possible to calculate in an easy way for instance the “total number of sensors” by using the fol-
lowing equations:
