Product Description:

The 2NC303.60-1 is a controller module manufactured by B&R Automation for the System 2010 Controllers series. It serves a supervisory role in industrial automation lines, where one module must coordinate signal handling, timing, and local control tasks across connected devices. The unit issues deterministic I/O updates, executes user logic, and supplies regulated encoder power so that coordinated motion and process functions can run without external PCs. Because signal processing and control are handled locally, the delay between sensing, decision-making, and actuation remains short and predictable.

This model digitizes field signals with a resolution of 12-bit, and its outputs use the same granularity for processed values. A continuous output capacity of 1 A allows direct operation of valves or relays, while internal counters run at up to 56 MHz and store positions in 21-bit registers for fast rotary or linear encoders. Each instruction is completed in 0.8 microseconds, and gating tasks use a base period of 7.69 microseconds, which supports tightly timed control responses. Signal fidelity is supported by a 500 Hz input filter and a 1 kHz output filter, while a 700 Hz pulse source and dual-ported 384-byte SRAM support motion handling and real-time data exchange between the application and communication layers. That timing performance is useful in applications that must evaluate encoder changes and switch outputs within very small intervals.

The housing measures 285 × 80 × 185 mm, and it includes a system RAM bank of 256 KByte SRAM for variables and diagnostics between scans. External encoders can draw up to 160 mA from a dedicated supply held at 24 V ±10 %, which helps maintain stable reference levels under cable losses and longer wiring runs. The controller also supports positioning with a path resolution of 0.05 mm, and the available memory supports the working data needed by cyclic programs and diagnostic routines. Its layout supports dense installation without shifting motion control tasks to a separate computer.
