The Telco MPA 21 series are 2‑channel photoelectric amplifiers designed to process signals from paired remote photoelectric sensors (such as LT and LR series) in industrial automation applications. These amplifiers are capable of monitoring two independent optical sensor pairs simultaneously, enabling object detection, presence control, and position monitoring across conveyor lines, packaging equipment, and material handling systems. With dual channel outputs, adjustable sensitivity, and selectable detection modes, the MPA 21 series provides flexible integration into automation control systems.
Each variant in the MPA 21 family differs by supply voltage and output type to match various plant requirements. These amplifiers mount on a standard 11‑pole DIN socket and provide manual potentiometers for sensitivity adjustment and light‑on/dark‑on selection per channel. Clear LED indicators for power and individual channel outputs help with quick alignment and diagnostic feedback during installation and maintenance, ensuring reliable operation in industrial environments.
