NIOPERATING INSTRUCTIONS AND SPECIFICATIONS NI 9505

only.

• Tie the motor cable shield to chassis ground at the motor side 

only.

• Tie the encoder cable shield to COM at the encoder side only.

• Wire encoder signals and their ground connections separately 

from all other connections to prevent lost encoder counts.

• Route wires along the machine frame to reduce high frequency 

noise.

• Add clamp-on ferrites to cables to further reduce emissions.

• Add a balun to the power cable to attenuate conducted and 

radiated emissions

Channel-to-COM ..............................0 to +30 VDC max, 

Measurement Category I

Isolation

Channel-to-channel ....................None

Channel-to-earth ground

Continuous ...........................60 VDC, 

Measurement Category I

Withstand .............................750 Vrms, verified by a 5 s

dielectric withstand test

Measurement Category I is for measurements performed on 

circuits not directly connected to the electrical distribution system 

referred to as MAINS voltage. MAINS is a hazardous live electrical 

supply system that powers equipment. This category is for 

measurements of voltages from specially protected secondary 

circuits. Such voltage measurements include signal levels, special 

equipment, limited-energy parts of equipment, circuits powered by 

regulated low-voltage sources, and electronics.

Caution Do not connect the NI 9505 to signals or use for 

measurements within Measurement Categories II, III, or IV.
