I-7530A RS232/422/485 To CAN Bus Converter

Description

The I-7530A RS232,RS422 or RS485 to CAN Bus converter makes it possible to connect a host PC/HMI Display into a CAN Bus Network. Similarly it can also allow standard RS232 devices to be connected to a CAN Bus Network.

The PC can be the CAN host, monitor or HMI to access/control the CAN device through the CAN network via the I-7530 Converter. The programmable RS-232 device (For example: I-8411/I-8431/I-8811/I-8831/W-8341/W-8741 embedded controller) can use the serial port to connect to the CAN network via the I-7530 module.

The I-7530A is designed to unleash the power of CAN bus via Serial communication method. It accurately converts messages between CAN and RS-232 networks. This module allows you to communicate with CAN devices easily from any PC or from any device with a Serial interface.

Features

3000V isolation on CAN side
The CAN port of I-7530A has 3000V isolation. This isolation can protect the local RS-232/485/422 devices from  damaging signals coming from the CAN network.

Watchdog inside
The I-7530A Watchdog has a hardware reset circuit to monitor the I-7530A's operational status. When working in harsh or noisy environments, the I-7530A may be affected by the external signal. The circuit will help the I-7530A to continue to operate.

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