Descripción Reseñas

The Allen-Bradley 1756-DICAM is a specialized digital cam switch module designed for the ControlLogix automation platform. By utilizing an onboard Motorola ColdFire CPU, this single-slot module offloads complex position-proportional logic from the primary controller, executing high-speed cam scheduling directly at the hardware layer. This autonomous operation optimizes execution rates for rotational position sensing and sequential tool triggering, reducing system latency and mechanical downtime in high-speed applications such as packaging, rotary assembly, and bottling.

Features

Co-Processing Architecture: Executes high-speed cam logic independently to minimize controller scan time impact.
High-Capacity Profiles: Supports up to 10,000 programmable cam steps for complex, non-linear mechanical profiles.
High-Density I/O: Features 8 field inputs and 24 sourcing (positive-switching) digital outputs.
Flexible Output Current: Outputs support 200 mA or 400 mA per point, depending on wiring and load requirements.
Dynamic Configuration: Enables rapid recipe hot-swaps without requiring firmware resets.

Applications

The 1756-DICAM is ideal for high-speed industrial machinery requiring precise, sub-millisecond switching behaviors. Common applications include:

Rotary packaging and bottling lines
High-speed material handling systems
Automated assembly and stamping machinery
Dynamic tool triggering based on rotational position
