S3R8 Two-Channel Isolated CAN Controller

The S3R8 Two-Channel CAN Controller delivers professional-grade CAN bus communication with two fully isolated CAN channels, built-in TVS protection, and flexible connectivity options. Whether you're developing embedded systems, industrial automation setups, or automotive diagnostics tools, this compact controller gives you reliable, high-speed CAN 2.0A/2.0B communication at rates up to 1 Mbps.

Key Features

  • Dual Isolated CAN Channels: Independent CAN1 and CAN2 paths support both CAN 2.0A and CAN 2.0B protocols at data rates up to 1 Mbps — ideal for demanding multi-bus environments.
  • Electrical Isolation & TVS Protection: Digital and power isolation combined with TVS components safeguard both the controller and CAN interfaces from voltage transients and electrostatic discharge.
  • Flexible Power & Connectivity: Accepts 7–36 V via terminal block input or 5 V via USB Type-C port. Supports firmware download, USB communication, and built-in 2.4 GHz Wi-Fi functionality.
  • Panel-Mount Enclosure: The compact enclosed format integrates cleanly into control panels and cabinets, with dedicated PWR, CAN1, and CAN2 LED indicators for instant status monitoring.
  • Reserved 120Ω Terminal Resistance: Pre-provisioned terminal resistance (default NC) for straightforward CAN bus termination configuration.
  • Onboard Peripherals: Includes a real-time clock and SH1.0 pin headers to expose GPIO for custom integrations.

Frequently Asked Questions

Q: What CAN protocols does the S3R8 Two-Channel CAN Controller support?

A: The S3R8 controller supports both CAN 2.0A (standard 11-bit identifier) and CAN 2.0B (extended 29-bit identifier) protocols, with communication rates up to 1 Mbps on each of the two isolated CAN channels.

Q: How is the S3R8 powered, and can it be used in both lab and field environments?

A: Yes — the S3R8 accepts a wide voltage range of 7–36 V via terminal block for industrial or automotive power supplies, or 5 V via USB Type-C for bench and development use, making it versatile for both lab prototyping and deployed field installations.

Q: What kind of protection does the S3R8 offer for its CAN interfaces?

A: The controller features TVS tube protection, electrostatic discharge (ESD) safeguards, and both digital and power isolation on each CAN channel. A reserved 120Ω terminal resistance is also provisioned (default NC) for proper CAN bus termination when needed.

Q: Does the S3R8 support wireless communication?

A: Yes. In addition to wired USB communication and firmware download capability, the S3R8 includes built-in 2.4 GHz Wi-Fi for wireless data transfer and remote integration into networked systems.
