Module13.2 PwrCAN

SKU:M139

Description

PwrCAN Module 13.2 is a multifunctional module designed for the PwrCAN bus, integrating isolated CAN communication and DC 9-24V power bus. The module also includes Pwr485 (with isolation) bus functionality and can provide isolated 5V power supply to the M5 host. The CAN communication part uses the CA-IS3050G isolated transceiver, and the RS485 part uses the CA-IS3082W isolated transceiver. The GPIOs related to CAN and RS485 communication can be selected through dip switches, and the 120-ohm terminal resistance at the CAN and RS485 outputs can also be selected through dip switches. The module's power bus supports DC 9-24V wide voltage input, with the DC socket directly connected to the HT3.96 and XT30 power parts. The built-in isolated power module F0505S-2WR3 provides power to the M5 host. This module is suitable for fields such as robot control, protocol conversion, industrial automation, automotive communication systems, intelligent transportation, and building automation.
