Connecting the Signal Input Cables

This section describes how to connect the signal input cables.

Terminal Configuration and Signal Types

Voltage input
Resistance temperature detector
not available
+.........................................High-voltage terminal (terminal for high-voltage input signals)
–..........................................Low-voltage terminal (terminal for low-voltage input signals)
Input configuration
Analog voltage
Thermocouples
A/D resolution
Filter
2-6
DC voltage
Item
Isolated input, scanning
20, 50, 100, 200, 500 mV/F.S.; 1, 2, 5, 10, 20, 50 V/F.S.; 1-5V
K, J, E, T, R, S, B, N, W (WRe 5-26)
16-bit (Effective resolution: About 1/40,000 of the +/- range)
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 ob-
tained in a sub-sample (5 seconds) is used.
Terminal configuration
Thermocouple input
Current input
DC current
Description
Compensation wire is
used if it is required.
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.
