I-8120W

1 Port Intelligent CAN bus Communication Module

  Price:  $499.00  

Features

The CAN (Controller Area Network) is a serial communication bus especially suited to interconnect smart devices to build smart systems or sub-system. It efficiently supports distributed real-time control with a very high level of security. In CAN networks, there is no addressing of subscribers or stations in the conventional sense, but instead prioritized messages are transmitted. As standalone CAN controller,I-8120W with WinPAC/LinPAC/iPAC series MCU (main control unit) represents an economic solution. It has one CAN communication port with 5-pin screw terminal connector, and is useful for a wide range of CAN applications. Besides,I-8120W uses the new Phillips SJA1000T and transceiver 82C250, which provide both CAN 2.0A and 2.0B specific, re-transmission function, bus arbitration and error detection.

Combining the benefits of WinPAC/LinPAC/iPAC series MCU without increasing the CPU loading heavily, it could be a powerful multi CAN port programmable device server by driving the program in the 186 CPU ofI-8120W. It can also communicate with other kinds of communication interface, such as RS-232/RS-485/Ethernet ports to be a programmable device server. Therefore, users can design the various applications between different communication protocols.
