2.5 Connecting the Signal Input Cables

This section describes how to connect the signal input cables.
During wiring, confirm that the signal's supply source is turned OFF to prevent electrical shocks.
Also, position the GL240 input cable away from any power lines and ground cables.
Terminal Configuration and Signal Types
Terminal assignment of standard terminal and Withstand high-voltage high-precision terminal is common.

Filter operation is on a moving average basis.
The average value of the set sampling count is used.
If the sample interval exceeds 5 seconds, the average value of data
obtained in a sub-sample (5 seconds) is used.

Shunt resister
Ex: The current is converted to the voltage in the shunt register.
For 4 to 20mA current input, installing 250 ohms (0.1%)
resister for converting 1 to 5V.
* 250 ohms shunt register is the option B551.
