Introduction:
The CAN-22 isolation hub is a cost-effective industrial grade product that can be used in industrial automation equipment, security systems, smart instrumentation and more. The hub provides 1.5KV electrical isolation, introduces a failure isolation mechanism, detects bus status in real time and automatically isolates the fault bus, ensuring normal operation of other ports, providing great convenience for engineers and technicians to install and maintain. The product is modular in design and can be used in combination. It is mounted on a standard 35mm DIN rail. The terminals are detachable, small in size and light in weight, which saves a lot of space and time for on-site installation.

Indicator light:
D1 green light flashes CAN1 data receive / answer (ACK) indication
D2 green light flashes CAN2 data reception / response (ACK) indication

Failure isolation function:
CAN-1 provides fail-isolation. When one of the bus data continues to be “dominant”, the other transceiver will trigger dominant.
The timeout (DTO) function isolates the fail-side bus and ensures that the normal side bus nodes remain in normal communication.
