3IP161.60-1 Programmable Controller

The 3IP161.60-1 is a compact and integrated programmable controller developed by B&R Industrial Automation, categorized as a core CPU unit of the B&R System 2005 series. It integrates a dedicated processing core, complete digital and analog I/O channels, and multiple communication interfaces into a single unit. This controller can operate independently as a standalone programmable controller for small and medium-sized automation systems, or serve as an extended control and signal processing unit in a larger distributed control architecture. Featuring an industrial-grade rugged design, built-in electrical isolation and strong anti-interference capability, it ensures long-term stable operation in complex industrial environments. Adopting standard backplane mounting, the module can be seamlessly installed on System 2005 racks, helping to save cabinet space and simplify the overall layout of automation systems.

The official model of the product is 3IP161.60-1, which is a standard single-width module of the B&R System 2005 series. Manufactured in Austria, it complies with B&R’s global industrial quality standards and international electrical safety regulations, and has obtained CE certification. The module has an IP20 protection rating and is designed for installation inside standard industrial control cabinets. It is powered by the 24 VDC power supply from the System 2005 backplane. In terms of storage configuration, it is equipped with 1.5 MB FlashPROM for user program storage and 850 KB retentive SRAM for process data storage, which can retain data after power-off. Although it is a legacy model of the System 2005 series, it is still widely supplied as a spare part for existing automation equipment worldwide. The entire lifecycle including configuration, programming, debugging and maintenance of this controller is completed through B&R Automation Studio software.

As a core programmable controller in industrial automation systems, the 3IP161.60-1 undertakes multiple core tasks such as user program execution, logic control, field signal acquisition, analog closed-loop regulation and data communication. When working as a standalone controller, it can independently complete all control functions for small automation equipment without additional expansion modules. When used as an extended control unit, it expands the I/O access and communication capacity of the main control system. The integrated digital input channels collect on-site switch signals from sensors and limit switches, while digital output channels drive low-power actuators such as relays and contactors. The analog input channels acquire continuous process signals from transmitters, and analog output channels output adjustable signals to control frequency converters, proportional valves and other analog execution devices. The controller is fitted with one RS232 serial interface and one electrically isolated CAN bus interface, supporting connection with human-machine interfaces, debugging tools and CANopen fieldbus devices to realize point-to-point communication and networked control. All signal channels are equipped with input filters and independent electrical isolation to suppress on-site electromagnetic interference and guarantee stable signal transmission and system operation.

This controller adopts the dedicated CPU for the B&R System 2005 series, with a fast processing speed. The execution speed for bit instructions reaches 0.1 microseconds, and that for typical logic instructions is 0.5 microseconds, ensuring rapid logic response and data processing. For digital I/O, it provides 12 sink-type digital input channels supporting 24 VDC signals, with built-in interference filtering circuits. It also has 12 digital output channels working at 24 VDC, and the rated current of each single channel is 0.1 A, meeting the driving requirements of conventional low-power switching devices.

In terms of analog signal processing, the controller is configured with 6 analog input channels and 6 analog output channels, both supporting a signal range of ±10 V. The analog input channels adopt 14-bit resolution to achieve high-precision collection of continuous process signals, while the analog output channels use 12-bit resolution to deliver accurate analog regulation. Each terminal block integrates independent +10 V and -10 V power supply circuits, facilitating on-site wiring and signal matching.

Regarding communication performance, the RS232 serial interface supports standard point-to-point serial communication for equipment debugging and short-distance data transmission. The CAN bus interface features complete electrical isolation and network expansion capability, and is compatible with the CANopen protocol to adapt to multi-node fieldbus networking scenarios. For environmental adaptability, the operating temperature ranges from 0°C to 60°C, the storage temperature ranges from -25°C to 70°C, and the applicable relative humidity is 5% to 95% non-condensing, which can adapt to most indoor industrial working conditions. Multiple LED status indicators are arranged on the panel to display the real-time status of power supply, operation, communication and I/O channels, which is convenient for on-site personnel to conduct status monitoring, fault diagnosis and routine maintenance.

During on-site installation and commissioning, dedicated supporting terminal blocks need to be purchased separately for signal wiring and power connection. The controller is fully compatible with standard backplanes, racks and expansion slots of the entire B&R System 2005 series. To realize communication functions, supporting RS232 serial cables and CAN bus cables are required. B&R Automation Studio serves as the unified software platform for configuration, programming, debugging and fault diagnosis of this programmable controller. It can work in conjunction with various industrial standard peripheral devices including sensors, actuators, frequency converters and human-machine interfaces.

This programmable controller is fully compatible with all products in the B&R System 2005 series, and can be deployed as a standalone main controller or an extended control unit in distributed control systems. It is widely applied in multiple industrial fields such as general mechanical manufacturing, packaging machinery, textile equipment, food and beverage processing and small-scale process control systems. It is especially suitable for compact automation equipment and small and medium-sized control systems that require integrated logic control, analog signal processing and fieldbus communication, including special-purpose machines, automated assembly lines, small processing equipment and distributed on-site control nodes. Its highly integrated design effectively reduces the total number of modules in the control cabinet, saves installation space and lowers the overall cost of system construction and subsequent maintenance.

The 3IP161.60-1 is an original genuine product of B&R, manufactured in accordance with the group’s strict global quality management system. It has passed CE and other international safety and electromagnetic compatibility certifications, fully complying with unified international industrial standards. The controller boasts excellent electromagnetic compatibility and anti-interference performance, with a long service life, and can operate continuously and stably for a long time in harsh industrial environments. Supported by a complete quality assurance system and global after-sales service network, it can fully meet the long-term continuous operation requirements of various industrial sites.
