The 1785-L46B is a PLC-5 series controller manufactured by Allen-Bradley. This controller is at the forefront of the controlling architecture by bringing together systems with the help of the Ethernet, ControlNet, DeviceNet or IP network. The 1785-L46B can be used to connect with ControlLogix controllers, MicroLogix controllers, SLC 500 controllers, and so on. This is one of the Protected PLC-5 controllers. The 1785-L46B is designed to have a memory of 48K SRAM. The maximum I/O that is expected is 2048 any mix or 2048 inputs and 2048 outputs (complementary). This controller functions properly at a backplane current of 3.3 Amps with a power of 17.3W. The number of I/O Chassis that can be supported by the 1785-L46B can vary. It has a total of 62 I/O chassis while the extended amount is 0. Up to 32 Remote I/O are supported but no ControlNet I/O are supported.

For communication purposes, 4 DH+/remote channels are used in this controller. A local area network called the Data Highway Plus (DH+) is a network system designed to support data acquisition and remote programming for factory-floor applications. A small peer-to-peer network can be put into place by using DH+ communication modules to implement it. Users can limit access to the critical areas of programs, restrict the use of controller operations, or selectively guard the controller memory and I/O by using protector PLC-5 controllers like the 1785-L46B. Safety-yellow labels, which are distinctive on the controller, identify the protected PLC-5 controller. Class privileges can be assigned by using the programming software with specific user accounts or functions such as maintenance engineer, system administrator, or operator. This series of controllers can expand the validity and security of the system beyond the default settings with the help of the password-and-privilege options present on the other PLC-5 controllers.
