When a machine or vehicle needs to control several motors while also reading sensors and communicating with other electronic controllers, a general-purpose I/O module may not provide the required motor-control outputs. The MRS Electronics 3CH 10A Motor Controller combines motor outputs, analog inputs, PWM-capable I/O, CAN communication, and optional LIN in a compact controller.
Mrs Electronics (1.162.300.0000) 3CH 10A, CAN0 with Wakeup, Motor Controller
The controller is designed for applications where multiple motor channels need to be managed from a single electronic control unit. It provides 6 halfbridge and 3 fullbridge configurations, giving the controller flexibility for different motor-control arrangements. The motor current is rated at 10 A, while the switching current is specified at 5 A at 85°C.
Alongside the motor outputs, the controller provides 8 analog inputs for connecting sensors and monitoring machine signals. It also includes 2 I/Os with analog input, PWM-capable output with integrated current measurement INA, and digital output capability. This combination allows motor control and sensor acquisition to be handled within the same compact controller.
For machine networking, the controller includes one CAN interface and one CAN FD interface. CAN FD capability allows the controller to communicate within CAN-based electronic control architectures, while the optional LIN interface provides an additional communication option for connected devices.
The controller is programmed through MRS Applics Studio and is designed for demanding operating environments. Its PA66GF30 housing provides IP6K8 protection, while the -40°C to +85°C temperature range and 8-32 V operating voltage support use in harsh mobile and industrial applications.
The available CAN, sensor, I/O, and motor connections provide a compact interface for distributed machine control. With its multiple bridge configurations, 10 A motor current capability, CAN FD communication, sensor inputs, and rugged housing, the controller can be integrated into motor-driven equipment where space and environmental durability are important.
