Recording instrumentation signals (4-20 mA)
This section introduces a method for recording current output (4-20 mA) from instrumentation
devices.
Average values for each minute can also be recorded using numerical calculations.
• Applicable modules: U8550, U8551, U8552, U8553, LR8530, LR8531, LR8532, LR8533
• You will need: an input cable and a 250
Ω
shunt resistor
Instructions
1
Connect the input cable and the 250
Ω
shunt resistor to the channel being measured.
Connect the shunt resistor between the positive and negative input terminals.
See “Connecting voltage cables and thermocouples” in the Quick Start Manual.
2
Connect the input cable to the instrumentation device’s current output (4-20 mA) terminal.
3
On the [Unit] screen, set the data refresh interval to [Auto].
