I-7530A

I-7530A

The I-7530A is an RS-232/422/485 to CAN converter. It is a member of the I-7530 serial family, and inherits all of the features of the I-7530. The CAN interface of the I-7530A follows ISO 11898-2 specifi cation, the maximum CAN baud is up to 1 Mbps. There is one COM port in the I-7530A. As the I-7530A runs, it only receives the commands from one of these COM interfaces (i.e. from the RS-232, RS-485 or RS-422 interface) at the same time, but the CAN messages will be forwarded to all of these COM interfaces.

    Description

    Moreover, we expand the functionalities of I-7530A for some special application. In pair connection mode, I-7530A can be used to connect PC with other RS-232/485/422 devices at the same time. The application architecture may be as follows.

     

    3000V isolation on CAN side
    The CAN port of I-7530A is an isolated with 3000V isolation. This isolation can protect the local RS-232/485/422 devices from the damage signal coming from CAN network.

    Watchdog inside
    The I-7530A Watchdog is a hardware reset circuit to monitor the I-7530A’s operation status. When working in harsh or noisy environment, the I-7530A may be down by the external signal. The circuit may let the I-7530A to work continuously and never halt.

    Power and Error indicator display
    There are two indicators on the I-7530A.The power indicator can help user to check whether the I-7530A is standby or transmitting/receiving messages. The Error indicator will be turned on when some errors occur on the I-7530A.
