Physical Specifications
The 171CBU98090 measures 144 mm in width and 53.47 mm in depth. Its height is 60.6 mm. The product weight is approximately 0.163 kg. The unit uses a Lexan material construction. It mounts securely on a standard 35 mm symmetrical DIN rail. The IP20 rating provides basic environmental protection.
Operating Conditions
This model operates within 0 °C to 60 °C ambient temperatures. The storage temperature ranges from -40 °C to 85 °C. Furthermore, it withstands 5 % to 96 % relative humidity without condensation. The shock resistance reaches 15 gn during 11 ms sinusoidal vibrations. Additionally, the 171CBU98090 resists electrostatic discharge up to 6 kV contact. It offers 8 kV air discharge protection as well.
Pre-Installation Preparation
Firstly, ensure the system power is completely disconnected before starting the installation. Use appropriate ESD protection when handling the 171CBU98090. Prepare a clean workspace and gather the necessary tools. Confirm that the 35 mm DIN rail is securely mounted inside the cabinet. Verify the I/O base compatibility for this processor.
Mounting Procedure
Next, attach the 171CBU98090 directly onto the Momentum I/O base. The processor fits any compatible Momentum I/O base. Snap the locking tabs into the corresponding slots on the base. Then, connect the 12-pin power and communication connector between the units. The processor snaps securely onto the base with multiple connection points. For high vibration environments, use the reinforcement kit (170 XTS 120 00). This kit provides additional stability for the assembly.
Electrical Connections
After mounting, connect the Ethernet and serial communication cables. The 171CBU98090 uses an RJ45 connector for Ethernet. Connect the RS485/RS232 cables to the designated serial port. The USB port provides direct access for programming and diagnostics. Always disconnect communication cables before attaching or detaching the processor. This prevents potential electrical hazards.
Post-Installation Checks
Finally, connect the system power and verify the unit powers up correctly. Observe the LED indicators for proper status signals. The RUN LED confirms normal processor operation. The ERR LED indicates any system faults. Additionally, the I/O LED shows module status. Check the Ethernet link and activity LEDs for network connectivity. Confirm that Unity Pro software recognizes the 171CBU98090 properly.
