• Power Requirements: Requires a +5 VDC power supply, with a current consumption of 825 mA and a power of 4.1 W; when the current reaches 1.1 A, the power is 5.5 W.

• System Network Capability: Based on the Cnet (INFI-NET) network architecture, the entire system can support more than 62,000 nodes. Among them, there are 250 Cnet-to-Cnet interface nodes; in a single network, any combination of Cnet-to-HCU (Highway Communication Unit) or Cnet-to-computer interfaces can support 250 nodes.

• Communication Rate: Supports communication rates of 10 Mbaud, 2 Mbaud, or 0.5 Mbaud, which can be flexibly selected according to actual industrial application scenarios and system requirements to ensure efficient data transmission.

• Physical Specifications: The module is an independent printed circuit board, occupying only one slot in the Module Mounting Unit (MMU). The circuit board integrates a microprocessor-based communication circuit to realize connection with the Cnet network, and interacts with the INNPM22 module through a dedicated I/O expansion bus segment. The module weighs approximately 2 kg.
