I-8124W-G - 1 Port DeviceNet Master Slot
by ICP DAS

The CAN (Controller Area Network) is a serial communication protocol, and efficiently supports distributed real-time control with a very high level of security. It is especially suited for network "intelligent" devices as well as sensors and actuators within a system or sub-system. In CAN networks, there is no addressing of subscribers or stations in the conventional sense, but messages are transmitted according to highest priority. The I-8124W CAN controller can represent an economic solution of DeviceNet application and be a set as a master device. It is a "Predefined Master Connection Set" and supports Group 2 only Server functions to communication with slave devices. With an independent CAN bus communication port having a 5-pin screw terminal connector, it has the ability to cover a wide range of DeviceNet applications. The I-8124W uses the new CAN controller Phillips SJA1000T and transceiver 82C250/251, which provides for bus arbitration, error detection with auto correction and re-transmission function. It can be installed on a WinPAC or ViewPAC series PAC devices. It's most popular application is in the industrial automation, building automation,vehicle, marine, and embedded control network.
