The 1769-L35CR is a specialized CompactLogix processor from Allen-Bradley designed for ControlNet networks. This controller features redundant ControlNet communication ports for enhanced network reliability. It is specifically built for applications requiring deterministic and high-availability networking. Therefore, this module serves as an excellent choice for critical control system implementations.
To begin with, the 1769-L35CR logic module provides 1.5 MB of user memory for program and data storage. Additionally, it supports up to 30 Compact I/O modules distributed across a maximum of 3 I/O banks. These banks connect using up to 2 expansion cables for flexible system layout. Meanwhile, each I/O bank requires its own separate power supply for proper operation.
Communication capabilities are a key feature of this model. For instance, the 1769-L35CR includes two ControlNet ports designated as Channel A and Channel B. This dual-port configuration supports redundancy for critical control applications. Furthermore, it features a NAP port (Network Access Port) for temporary connections. The controller also includes an RS-232 serial port for programming and basic communication. Specifically, you can connect devices using 1756-CP3 or 1747-CP3 cables through this serial interface.
In addition, the backplane current draw is 680 mA at 5 Volts DC. Its heat dissipation is rated at 4.36 Watts maximum. The controller must be strategically placed within four power supply modules of the power supply. Moreover, only one 1769-L35CR can be connected to a Logix system at any given time. This uniqueness ensures proper system operation and prevents conflicts.
This controller operates reliably in standard industrial conditions. For example, its operating temperature range is from 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit). Meanwhile, the storage temperature ranges from -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). It also functions within a non-condensing relative humidity range of 0 to 95%.
Furthermore, the 1769-L35CR demonstrates good physical durability. Specifically, it withstands an operating vibration of 5 g at 10-500 Hz. The operating shock rating is 20 g for both DIN Rail and panel mounting installations. Additionally, the mounting torque specification ranges from 1.1 to 1.8 Nm for secure installation.
Proper installation ensures reliable performance of the 1769-L35CR processor. First, the unit supports both DIN Rail and direct panel mounting without requiring a chassis. This flexibility simplifies integration into existing control cabinets. Furthermore, the power supply distance rating requires careful positioning relative to the power supply.
Next, wiring must follow specified guidelines for safety and performance. Use copper wire rated for 90 degrees Celsius. Solid wire sizes from 22 to 14 AWG are acceptable. For stranded wire, use sizes from 22 to 16 AWG. In addition, the maximum wire insulation rating is 30 Volts. Finally, always observe proper torque specifications when tightening connections.
