The HAWE CAN-IO 14 series is a specialized hydraulic valve PLC that uniquely integrates a freely programmable logic controller with high-performance proportional valve amplifiers. Designed and manufactured by HAWE Hydraulik SE, a leader in mobile and industrial hydraulic systems, the CAN-IO 14 is engineered for the precise and reliable control of complex hydraulic functions. It is available in two variants—the CAN-IO 14+ and the enhanced CAN-IO 14 PRO—providing scalable solutions for a wide range of mobile machinery and industrial automation applications. The device is housed in a remarkably compact, IP67-rated enclosure measuring just 60 x 60 x 30 mm, allowing it to be mounted directly on machinery in harsh outdoor environments where it is exposed to dust, moisture, and extreme temperatures ranging from -40°C to 85°C.

At its core, the CAN-IO 14 functions as a powerful control node. It provides up to 8 IPWM (Intelligent Pulse Width Modulation) outputs for directly driving proportional solenoids with high precision, eliminating the need for separate amplifier cards and significantly reducing wiring complexity. It also features up to 16 analog inputs for reading data from a wide array of sensors, including joysticks, pressure transducers, and position feedback devices. A key differentiator of the CAN-IO 14 is its ability to perform feedback measurement directly at the valve outputs, enabling closed-loop control strategies that ensure highly precise and repeatable valve movements. All inputs and outputs are freely parametrizable, allowing the controller to be tailored exactly to the specific requirements of the hydraulic system.

Flexibility is further extended through the controller's communication and programming capabilities. The CAN-IO 14 is equipped with up to two CAN bus interfaces, enabling it to function as a CAN slave within a larger distributed control system or to communicate with other intelligent devices. It supports the CANopen protocol and can be configured to act as a remote I/O station, receiving commands and transmitting data back to a master PLC, thereby reducing wiring costs in complex machinery. For development, HAWE offers unparalleled flexibility. Engineers can program the CAN-IO 14 using HAWE eDesign, a cloud-based, graphical programming interface that requires no prior coding knowledge and is ideal for low-to-medium complexity projects. Alternatively, for more advanced or complex applications, the controller can be programmed directly in C, providing full access to its hardware capabilities. Programs are loaded onto the device via the CAN bus using the free HAWE eUpdater tool. A built-in RS232 interface provides additional connectivity for diagnostics and legacy device integration.

The CAN-IO 14 is purpose-built for the demanding world of mobile hydraulics and industrial automation. Its rugged IP67-rated housing ensures reliable operation in the presence of dirt, dust, and water jets, making it ideal for direct on-machine mounting in construction equipment, agricultural machinery, forestry vehicles, and material handling systems. In these applications, the CAN-IO 14 excels at controlling proportional valves for functions such as boom positioning, steering, and drive control. It is equally at home in stationary industrial settings, where it can manage complex hydraulic power units, presses, and machine tools. The CAN-IO 14 PRO variant offers enhanced processing power and additional features for more demanding control tasks. With its unique combination of integrated intelligence, robust hardware, and open programming environment, the HAWE CAN-IO 14 provides a compact, flexible, and highly reliable solution for the precise control of modern hydraulic systems.
