Connecting the Signal Input Cables

This section describes how to connect the signal input cables.

Terminal Configuration and Signal Types

Connection diagram

DC voltage input
Voltage input
Resistance temperature detector input
Lead wire resistance should
be 10Ω or less per wire,
three wires need to be same length.
+................................. High-voltage terminal (terminal for high-voltage input signals)
– ................................. Low-voltage terminal (terminal for low-voltage input signals)
b ................................. Dedicated terminal when connecting resistance temperature detector
* Resistance temperature detector input terminals A (+) and B (-) are isolated within each channel. Terminal b
is shorted within all channels.

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.
