For More Information | |
- Built-in DeviceNet (1790D) or PROFIBUS DP (1790P) I/O adapter and up to 32 I/O points.
- Each digital I/O base block supports up to three CompactBlock LDX expansion blocks.
- D-shell or screw-clamp I/O connectors.
- DeviceNet base blocks receive power from the DeviceNet network while the PROFIBUS DP base blocks require a separate 24V DC power supply.
