This binary spacer module reserves bit addresses in the process image of a fieldbus node.
Both operating mode and bit width can be adjusted via DIP switches on the side of the module. The operating mode (inputs/outputs) can be selected via one DIP switch, the number of inputs or outputs (2, 4, 6 or 8) can be selected via two DIP switches.
The configuration is indicated via three LEDs.
The binary spacer module also acts as a supply module. It provides the 24 V field-side voltage for the downstream I/O modules via power jumper contacts.
