KH-UCANFD-X2I — 2-Channel Industrial USB CAN FD Adapter
Chengdu Kunhong Electronic Technology Co., Ltd.
Product Overview
KH-UCANFD-X2I is a 2-channel industrial USB CAN FD adapter in the CANmeleon family. It expands a computer, industrial PC or robot controller with two CAN / CAN FD channels and is designed for industrial automation, robotics, field debugging, fixed test stations and long-term deployment.
Unlike portable LITE and PRO adapters, X2I uses an aluminum enclosure with mounting holes, pluggable CAN terminal blocks, termination DIP switches, a side button and clear front-panel status indicators.
Status: Available
Typical Applications
- PLC, servo-drive, sensor and industrial-equipment CAN / CAN FD debugging
- Robot joint motors, end effectors, sensors and controllers
- Fixed installation in control cabinets, test fixtures and laboratory platforms
- Production-line testing, burn-in stations and long-term acquisition
- CAN FD bridging between industrial PCs, embedded controllers and host software
Highlights
- Aluminum enclosure with mounting holes
- Two CAN / CAN FD channels
- Pluggable 6-pin block or two independent 3-pin blocks
- Independent RES1 / RES2 termination DIP switches
- SYS, CAN1 and CAN2 indicators
- Side button for device operation and maintenance
- CANmeleon device and protocol-application management
- Windows, Linux, macOS, SocketCAN and python-can
Terminal Pinout
| Channel | Signal | Description |
|---|---|---|
| CAN1 | GND | Channel 1 reference ground |
| CAN1 | CAN1H | Channel 1 CAN High |
| CAN1 | CAN1L | Channel 1 CAN Low |
| CAN2 | GND | Channel 2 reference ground |
| CAN2 | CAN2H | Channel 2 CAN High |
| CAN2 | CAN2L | Channel 2 CAN Low |
The terminal can be supplied as one 6-pin block or two 3-pin blocks. Confirm CAN_H, CAN_L and GND before applying power.
Termination
| DIP switch | Channel | Function |
|---|---|---|
| 1 | RES1 / CAN1 | Enables channel 1 termination |
| 2 | RES2 / CAN2 | Enables channel 2 termination |
Enable the 120 Ω termination only when the adapter is at the corresponding end of the bus. Do not add extra termination at a middle node.
