The 1785-L40L is an Ethernet PLC-5 Programmable Controllers manufactured by Allen-Bradley that belongs to the 1785-L40 series (Cat. Nos. 1785-L11B, -L20B, -L30B, -L40B, -L40L, -L60B, -L60L, -L80B). The 1785-L40L features the Allen-Bradley Lithium Battery called the 1770-XYC module. It uses a backplane current of 3 Volts DC at 1800 mA, and the maximum operational thermal dissipation that this controller can have is 65.00 BTU/hour. This controller comes with an I/O number of 2048 maximum. The 1785-L40L comes with an internal circuit clock which has an accuracy variation of ± 5 minutes per month, and the temperature range for its operation is 32 to 140 degrees Fahrenheit and the humidity range is within 5 to 95%, non-condensing. The shipping dimensions for this controller are 2 inches x 11 inches x 6 inches. The average weight of the 1785-L40L controller is 3 pounds 1 ounce. It has 2 channels (for a remote I/O scanner, adapter, and DH+ link), 1 RS-232, RS-422, or RS-423 serial port, and 1 channel for an extended local I/O scanner is used for communication purposes in the 1785-L40L controller. The memory is 48k words SRAM.
It is not advised to change the Ethernet configuration jumper from the default setting, which is set at 802.3. This is the standard and usually the most accurate configuration. To maintain CSA certifications for hazardous areas, do not substitute any other battery for the 1770-XYC. PLC-5 programmable controllers, especially the 1785-L40L, can be called the hub of a control architecture. This combines future and current systems by using networks such as the EtherNet/IP, DeviceNet, and ControlNet. On top of that, it offers connectivity among MicroLogix, SLC 500, and ControlLogix controllers. The controlling and management functions are spread by using a distributed control system throughout a plant. Multiple processors are used in order to handle the management and control functions and to use a bus system for communication or a Data Highway. With minimized reference, better speed, better security, more information to make better-informed business decisions etc. features available. The 1785-L40L, along with the rest of the PLC-5 series, stands out in the market for its economy and efficiency.

About 1785-L40L
The Allen-Bradley 1785-L40L controller is a standard controller from the Allen-Bradley PLC-5 series with an extended I/O link. Its user memory capacity is 48,000 words. It is meant to be installed in an Allen-Bradley 1771 I/O chassis within a PLC-5 system, and it is made to be installed in the leftmost slot in the chassis. The 1785-L40L controller operates with an average thermal dissipation rating of 65 BTU per hour. It can be connected to a battery-backed static RAM module which can store its application data, and it can also be connected to a relay cartridge like the Allen-Bradley 1785-RC relay cartridge. The 1785-L40L controller can connect to ControlLogix controllers, SLC 500 controllers, and MicroLogix controllers.
The Allen-Bradley PLC-5 1785-L40L controller supports the ControlNet network, the DeviceNet network, and the Ethernet/IP network. The ports on this controller include the extended local I/O scanner port for communication, 1 serial port that can be used for RS-232 communication, RS-422 communication, or RS-423 communication, and 2 channels that can support remote I/O scanners and DH+ communication links. The shipping weight of the 1785-L40L controller is 3 pounds and 1 ounce, and its shipping dimensions are 2 x 6 x 11 inches. The ambient operating temperature range for the 1785-L40L controller is from 32 degrees Fahrenheit to 140 degrees Fahrenheit and it can tolerate relative humidity levels of 5 to 95% as long as there is no condensation. It supports up to 2048 analog I/O at a time and it also supports EPROM for backup.
