I-7532 CAN Bus 2-channel Isolated Bridge

Description

The I-7532 is a CAN bridge used to establish a connection between two CAN bus systems in a CAN network and has more facilities than the I-7531 (CAN Repeater).

The main benefit is that the transmission from each side of the Bridge is fully independent which allows the unit to be used to extend the total CAN network distance. Also if there are errors present (e.g. bit error) on one side of the I-7532 CAN bus system; the other side can still work correctly. The baud rate and filter setting of the two CAN channels on I-7532 can be different for higher flexibility and efficiency.

Features

• 82C250 CAN transceiver
• 2500 VRMS photo coupler isolation on the CAN side
• 3KV galvanic isolation among the power supply and 2 CAN channels
• Supports both CAN 2.0A and CAN 2.0B
• Fully compatible with the ISO 11898-2 standard
• Adjustable CAN bus baud rate from 5Kbps to 1Mbps or programmable user-defined baud rate
• Supports CAN bus message acceptance filter configuration 
• Provides I-7532 Utility for CAN bus message acceptance filter and user-defined CAN baud rate etc. configuration easily and quickly
• Supports firmware update via CAN1 of I-7532
• Built-in jumper to select 120Ω terminal resistor
• Watchdog inside
• Up to 100 CAN nodes on each channel
• Transmission distance up to 1 km on each CAN port
• Removable terminal block, Mount easily on DIN-rail
• 768 frame buffer for each CAN channel
• The baud of each channel can be different for higher flexibility
