3.5 Channels Configuration

Overview.

Universal inputs – mV, mA, V, THC, RTD and resistance.

Internal cold junction compensation.

Linearization – enables use of non-linearizing temperature transmitters or any electrical input.

Programmable fault levels and actions.

Digital filter – reduces the effect of noise on inputs.
Example A – setting up:

a current input of 4 to 20mA

displaying a range of 0 to 200psi

a fault detection level 10% above 200psi (engineering/display range) and 10% below 0psi (engineering/display range)

in the event of a fault being detected and/or the fault detection level being exceeded, the process variable is driven downscale.

Example B – setting up:


displaying temperature in °F

displaying a range of 0 to 2000°F

a fault detection level 10% above 2000°F (engineering/display range) and 10% below 0°F (engineering/display range)

in the event of a fault being detected and/or the fault detection level being exceeded, the process variable is driven upscale.
