Industrial Aluminum Alloy Din Rail 1-Channel CAN Repeater (Mini)

This industrial-grade intelligent CAN bus repeater is designed to increase the CAN bus load and extend the communication distance when the number of device nodes on the CAN bus exceeds 110 or the communication distance exceeds 10 km.

The two CAN channels can operate at different baud rates and comply with CAN specifications 2.0A (11-bit CAN identifier) and 2.0B (29-bit CAN identifier). It supports transparent, protocol-independent CAN message transmission, making it suitable for a variety of applications. Furthermore, it is compatible with various higher-level protocols such as CANopen, SDS, J1939, and DeviceNet.

This repeater can be configured with a CAN message receive filter, ensuring that only required data is transmitted through the repeater to other CAN networks. Configuration is done via the Ethernet web interface, including CAN channel baud rate, CAN message receive filter, and more. It is easy to use and takes effect immediately; once configured, the device is ready for operation without any further operation.

● Powered by an ARM Cortex-M4 processor with a main frequency of 240MHz.

● The CAN bus supports non-blocking communication at line speeds of 0-1Mbps, automatic baud rate scanning and matching, and custom baud rates.

● It supports CAN 2.0A and CAN 2.0B frame formats and complies with ISO/DIS 11898.

● The maximum transmit data rate is 8000 frames/second; the maximum receive data rate is 14000 frames/second. The CAN-side received message timestamp accuracy reaches 1µs.

● Each CAN channel has 6kV lightning protection and 3kV optical isolation. Each CAN channel has an independent shielded ground interface and is powered by a 3kV isolated DC-DC power supply. Communication signals are isolated by high-speed optocouplers.

● The CAN bus isolator can perform CAN network relay functions, storing and forwarding data between CAN networks of different speeds. Main applications are as follows:

  This series of products can increase the number of load nodes and extend communication distance, achieving network relay capacity expansion.

  The communication baud rate of each channel can be independently configured to interconnect CAN networks with different communication baud rates.

 Powerful ID filtering and data conversion capabilities allow precise acceptance of ID configuration to minimize CAN bus load. Alternatively, specific IDs and data can be modified to remove interference data and distinguish different devices.

Strong anti-interference capabilities prevent the user’s CAN device from being affected by strong interference and causing it to freeze.

● Supports one 10/100Base-T 100M Ethernet channel; supports automatic crossover detection (MDI/MDIX) for web configuration and system firmware upgrades.

●Dual DC power supply (5.08 terminal block):

Powered by a wide range of DC9-70V power supplies. The power supply features automatic polarity detection, eliminating the need to distinguish between positive and negative poles during installation.

Supports internal Isolation, redundant dual power inputs with reverse polarity protection.

● AC power supply (three-position plum blossom AC socket):

 Supports a wide input range of AC ~85-265V or DC 110-300V.

● Power supply features overload protection and complies with Industry Level 4 electromagnetic compatibility requirements.

●Strong lightning protection: protects against lightning strikes, induced high voltage, and surges.

● Fanless design for efficient heat dissipation, reducing repair time.

●Anodized aluminum alloy housing with IP40 protection rating withstands harsh environments.

● Can be mounted on a DIN rail or wall.

● Wide operating temperature: -40°C to +85°C; all models are 100% oven-tested.
