| Card has been installed for years with channels configured for 0-20mA. Were installing a new transmitter on one of the channels that is 4-20mA. Is it safe to change the channel configuration to with the processor running? |

| It's not safe and you have to change the configuration for 4-20mA |

Why would you do that? Just configure the range -25% to 100%
IE if your range is 0 to 1000 kpa for 4 - 20ma
PLC configuration would be -250 to 1000 kPa
That gives you an option for loop fail detection on your fuses, ect. |
