Danfoss Launches CAN 2 Current Solenoid-Mounted Microcontroller
Danfoss Power Solutions has introduced a compact solenoid-mounted microcontroller, known as CAN 2 Current (C2C), which is designed to work with the company’s cartridge valves, hydraulic integrated circuits (HICs), hybrid PVG/HIC valves, and open-circuit pumps. C2C connects these components to a machine’s CANbus to enable accurate and efficient actuation as well as simple diagnostics.
The C2C microcontroller offers a number of features:
- Communicates via controller area network (CAN) bus to provide closed-loop current control on one or two outputs
- Connectivity to CANbus enables real-time communication with machine controller, allowing status messages to be sent to operator display for more simplified diagnostics by eliminating the need for manual troubleshooting to identify solenoid issues
- Compliant with ISOBUS and SAE J1939 communication protocol
- Delivers repeatable and consistent control
- Can be used with on/off and proportional solenoids
- Available as either a single- or dual-channel device
- Single-channel device commands one coil while the dual-channel device can command two coils sequentially
- Quick and easy setup via Danfoss PLUS+1 Service Tool
- Configurable parameters include communication time guarding, dither, minimum and maximum current, and hold current
- Compact and robust design for space savings and durability in harsh applications
- Resin-potted construction offers protection from dust and dirt, as well as shock and vibration resistance
- IP67 ingress protection rating ensures long life in harsh off-highway mobile equipment environments
- Peak-and-hold control technology improves energy efficiency by reducing current in the hold phase to only the power required to maintain the solenoid’s position, thus holding the function
- Using retention current on extended-hold functions, such as clamping, reduces energy consumption by up to 70%, which can help reduce cooling needs and battery capacity in some battery-electric machines
