Banner Engineering B4-2L Photoelectric Amplifier Logic Plug Module

The Banner Engineering B4-2L Photoelectric Amplifier Logic Plug Module is a legacy plug-in module from Banner's B-Series designed for modular photoelectric sensor systems. It functions as the amplifier and logic stage, linking with a scanner block and power block in Banner installations to convert a detected photoelectric signal into a usable logic output. The module mounts in an octal-base socket on Banner control hardware, such as MRB or BRB chassis, a common arrangement for B-Series plug-in components. It provides a single output rated at 15 VDC and a maximum load of 0.25 A, suitable for feeding logic circuits or downstream devices within the Banner 15 V logic environment. This compact, plug-in logic module is designed to work with Banner photoelectric amplifiers and related logic blocks to form a complete sensing solution in automation and packaging lines. When integrated into a Banner system, the B4-2L enables straightforward signal conversion from the amplified sensor to control logic, supporting reliable operation in industrial sensing applications.
