28. Power There are two issues to consider if powering the MicroCAT externally e Limiting the communication IR loss to 1 volt if transmitting real time data higher IR loss will prevent the instrument from transmitting real time data because of the difference in ground potential e Supplying enough power at the power source so that sufficient power is available at the instrument after considering IR loss Each issue is discussed below Limiting Communication IR Loss to I Volt if Transmitting Real Time Data The limit to cable length is typically reached when the maximum communication current times the power common wire resistance is more than 1 volt because the difference in ground potential of the MicroCAT and ground controller prevents the MicroCAT from transmitting real time data V limit 1 volt IR jimit Maximum cable length R jjmit wire resistance per foot where I communication current required by MicroCAT 4 3 milliAmps see Specifications Example 1 For 20 gauge wire what is maximum distance to transmit power to MicroCAT if transmitting real time data For 4 3 milliAmp communications current R jimit V imit 1 volt 0 0043 Amps 232 ohms For 20 gauge wire resistance is 0 0107 ohms foot Maximum cable length 232 ohms 0 0107 ohms foot 21734 feet 6626 meters Example 2 Same as above but there are 4 MicroCATs powered from the same power supply For 4 3 milliAmp communications current R jimit V tim
