2.4 Connecting Signal Wires
Wiring Procedures
1. Turn OFF the power to the instrument.
2. Loosen the terminal cover attachment screw and lift up the terminal cover.
3. Connect the signal wires to the terminals.
4. Return the terminal cover to the original position and secure it with the screw.

Wiring the Universal Input Module
• Thermocouple input
• DC voltage input/DI input (contact)
• RTD input
• DC current input

Example: For 4 to 20 mA input,
shut resistance values should
be 250 Ω± 0.1%.

Note
• With the 10-CH Medium-Speed Universal Input module, the A and B RTD input terminals
are insulated on each channel, but terminal b is shorted internally on all channels.
• When the plate with screw terminal (model 772080) is connected to the 10-CH Medium-
Speed Universal Input Module, the terminal arrangement differs from that of clamp
terminals, so wire according to the markings on the terminal cover.
