2.5 Connecting the Signal Input Cables
This section describes how to connect the signal input cables.
During wiring, conrm 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 Conguration and Signal Types
Terminal assignment of standard terminal and Withstand high-voltage high-precision terminal is common.

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.

Item Description
Input conguration Isolated input, scanning
Measurement range 20, 50, 100, 200, 500 mV/F.S.; 1, 2, 5, 10, 20, 50, 100 V/F.S.; 1-5V
Thermocouples K, J, E, T, R, S, B, N, W (WRe 5-26)
A/D resolution 16-bit (Effective resolution: Approx. 1/40,000 of the +/- range)
Filter Off, 2, 5, 10, 20, 40
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.
