Specification

The 1756-M16SE is a dedicated SERCOS (Serial Real-time Communication System) interface module from Allen-Bradley’s ControlLogix platform, engineered for high-speed, deterministic motion control in demanding automation systems. It acts as a master node in a fiber-optic ring network, enabling synchronized control of up to 16 digital servo drives. This module is ideal for packaging, printing, material handling, and robotic applications where precise coordination is critical. Its fiber-optic communication eliminates electrical noise interference and simplifies cabling, while the hot-swappable design ensures minimal system downtime. Below are the comprehensive technical specifications derived from industry-standard documentation.
