Basic Information
The official model of the product is 3NC150.6, a standard single-width module manufactured by B&R in Austria, complying with the group’s global quality management system and international electrical safety standards. It has obtained CE certification and meets relevant EU directives on safety and electromagnetic compatibility. The module features an IP20 protection grade and is designed for indoor installation inside standard industrial control cabinets. It is powered by the system backplane, with a total power consumption of 5.0 W, including 3.5 W for 24 VDC and 1.5 W for 5 VDC. The product is equipped with an 8-pin terminal block and two 9-pin DSUB sockets for encoder connection, which are included in the standard delivery scope. All configuration, parameter setting, programming and debugging operations are implemented through the unified B&R Automation Studio software platform. As a mature model of the System 2005 series, it is still supplied as a spare part and replacement unit for in-service automation equipment worldwide.
Function and Positioning
As a core counting and positioning functional module, the 3NC150.6 is mainly used to collect pulse signals from incremental encoders, and perform high-speed counting, position calculation and speed measurement. It is equipped with two independent encoder input channels, supporting both symmetric and asymmetric encoder signals, and can connect to 5 V to 30 VDC incremental encoders to track the position, speed and direction of rotating shafts or linear moving mechanisms. The built-in 32-bit high-resolution counter ensures ultra-high counting accuracy and can realize up/down counting and homing functions, which can be monitored and controlled via both on-board LED indicators and supporting software.
In addition to counting and position detection, the module integrates two analog output channels with a signal range of ±10 V. It converts the calculated position and speed data into standard analog signals to drive external devices such as frequency converters, proportional valves and servo actuators, realizing closed-loop motion control. The input filter can be configured via software to filter interference pulses on site and ensure stable signal acquisition. It also features compensation current monitoring for analog outputs and short-circuit protection for output circuits, which effectively improves the safety and reliability of the system during operation. This module can be applied to single-axis position and speed control independently, or expanded as a signal acquisition and output unit in large-scale distributed control systems to expand the motion control capacity of the main system.
Core Performance Parameters
The module adopts a 32-bit counter core, providing a maximum input frequency of 100 kHz, which meets the high-speed pulse acquisition requirements of most industrial encoders. The encoder power supply supports 5 V to 30 VDC wide voltage range, with a working current of 40 mA at 5 VDC and 120 mA at 30 VDC. The two analog output channels have a 12-bit resolution, a basic accuracy of ±0.5% at 20°C, and a conversion time of 35 microseconds for all outputs, ensuring fast and accurate analog signal output. All analog outputs are equipped with short-circuit protection to avoid damage caused by external circuit faults.
In terms of environmental adaptability, the rated operating temperature ranges from 0°C to 60°C, the storage temperature ranges from -25°C to 70°C, and it can operate normally under a relative humidity of 5% to 95% non-condensing. Multiple LED status indicators are arranged on the module panel to display the working status of up/down counting, homing and compensation current of analog outputs, facilitating on-site personnel for real-time status observation and fault diagnosis. The integrated input filter supports software parameter setting to suppress electromagnetic interference and pulse noise in industrial sites.
General Matching Accessories
For on-site installation and wiring, dedicated encoder cables, power cables and signal connecting cables need to be equipped separately. The module is fully compatible with standard racks, backplanes and expansion slots of the B&R System 2005 series. To realize encoder signal connection, matching 9-pin DSUB connecting accessories are required, and the standard 8-pin terminal block is provided together with the product. B&R Automation Studio serves as the exclusive supporting software for parameter configuration, program editing, online monitoring and fault diagnosis of this module. It can be matched with various specifications of B&R incremental encoders, as well as peripheral devices such as PLCs, human-machine interfaces, frequency converters and actuators, to form a complete motion detection and closed-loop control system.
Applicable Equipment and Fields
The 3NC150.6 counter module is widely applied in industrial automation scenarios that require precise speed detection, position positioning and motion closed-loop control. It is commonly used in general mechanical manufacturing, packaging machinery, textile equipment, printing machinery, automated assembly lines and material handling equipment. It also performs excellently in machine tool auxiliary positioning, conveyor line speed regulation, lifting equipment position control and light-duty processing equipment. Whether it is single-axis independent motion monitoring or multi-axis linkage control, the module can deliver stable and reliable performance. Its highly integrated design reduces the number of peripheral components in the control cabinet, saves installation space and lowers the overall cost of system construction and subsequent maintenance. It is suitable for both new automation projects and technical transformation and upgrading of old production lines.
