The I/O ports can be expanded via serial communication over the CAN bus. Supports optocoupler inputs and dry-contact relay outputs. The SM-01-EXT board supports up to 20 input channels and 32 output channels. The SM.091CA.11 board supports up to 8 input channels and 8 output channels, and can be further expanded by another SM.091CA.12 board to add another 8 input channels and 8 output channels.
SM.091CA.11/SM.01.EXT I/O Expansion Board
Function Description: I/O ports can be expanded via serial communication over the CAN bus; Supports optocoupler inputs and relay outputs with 1,000 points; The SM-01-EXT board supports up to 20 input channels and 32 output channels; The SM.091CA.11 board supports up to 8 input channels and 8 output channels, and can be further expanded by an additional SM.091CA12 board to support another 8 input channels and 8 output channels.
I/O port expansion via the CAN bus; Suitable for all control systems; Optocoupler-isolated input, relay dry-contact output; The SM-01-EXT supports up to 20 input channels and 32 output channels, and can be configured via: A 4-bit DIP switch to select different operating modes (the program can support up to 40 floors);
