The 1769-CRL3 expansion cable is a necessary component for expanding your CompactLogix or DriveLogix system. This Allen-Bradley cable connects I/O banks using a right-to-left configuration. It effectively extends the 1769 bus communication lines to additional modules. Its 1-meter length provides flexibility for different rack layouts. This cable is a passive component. It does not require external power or configuration. It simply relays signals between connected banks. Therefore, it is a reliable and straightforward solution for system growth.
The 1769-CRL3 is built for industrial applications. Its operating temperature range is 0 to 60 degrees Celsius. The isolation voltage is rated at 30 Volts continuous. Additionally, the backplane current rating is 1.4 Amps at 24 Volts. This results in a power consumption of 33.6 Watts. The power dissipation is 7.5 Watts. Moreover, the cable measures exactly 1 meter or 3.28 feet in length. Importantly, this cable extends the communication bus only. It does not extend bus power. Consequently, each I/O bank must have its own dedicated power supply.
This cable is specifically a right bank-to-left bank expansion type. Its primary role is extending the 1769 bus lines. However, there is a critical system limitation to consider. A maximum of two expansion cables can be used in a single 1769 system. Therefore, this allows for a total of three banks of I/O modules. Each bank will need its own power supply. This design rule is essential for proper system operation. Besides this, the 1769-CRL3 is often used with the DriveLogix 5730 controller. It provides configuration flexibility. Specifically, it supports both horizontal and vertical system expansion.
The physical construction of the 1769-CRL3 suits standard industrial environments. It weighs approximately 350 grams. For storage, it can withstand temperatures from -40 to 85 degrees Celsius. Furthermore, the operational humidity range is 5 to 95% non-condensing. It can operate at altitudes up to 6561 feet. Its vibration tolerance is rated at 10-500 Hz at 5G. The operating shock rating is 30G when panel mounted. Meanwhile, it is 20G when DIN rail mounted. These specifications ensure reliable performance in demanding conditions. Always protect the cable from electrostatic discharge. Use static-safe workstations when handling it.
Installing the 1769-CRL3 is a simple procedure. First, always disconnect power before making any connections. This prevents electrical arcing and potential damage. Next, locate the right side of your I/O bank. Align the cable connector with the bus connector on the module. Then, use the tongue-and-groove slots to secure the cable cover. Finally, push the bus lever firmly to the left until it clicks. Ensure it is locked firmly to guarantee a proper electrical connection. This step is crucial for reliable communication. Panel mounting is also supported for flexible installation.

Q1: How many 1769 expansion cables can I use in one system?
A1: You can use a maximum of two cables. This allows you to create up to three banks of I/O modules, with each bank having its own power supply.
Q2: Does the 1769-CRL3 cable supply power to the connected I/O banks?
A2: No. This cable only extends the communication bus. Each I/O bank requires its own independent power supply.
Q3: What is the length of the 1769-CRL3 expansion cable?
A3: The cable is 1 meter or 3.28 feet long. This length is measured from end to end.
Q4: Which controllers are compatible with this expansion cable?
A4: The 1769-CRL3 works with CompactLogix controllers. It is also used with the DriveLogix 5730 controller to connect to a bank of Compact I/O.
Q5: What is the operating temperature range for this cable?
A5: The cable operates reliably in temperatures from 0 to 60 degrees Celsius, which is 32 to 140 degrees Fahrenheit.
