ABB D685A1156U01｜FMU BACK PLATE BOARD｜

D685A1156U01

Function
Multi bus compatible expansion
Simultaneously supporting standard fieldbus and FOUNDATION FF bus devices, it can be mixed with I/O and communication cards for unified data exchange.
Hot swappable fault-tolerant operation
Support non-stop replacement of cards, single channel failure does not affect the operation of other modules on the entire board, ensuring continuous production on the production line.
System data transfer
As a signal hub between the CPU and on-site instruments, it transmits measurement, control, and alarm data and interfaces with the upper monitoring system.
Stable power supply distribution
Unified allocation of 24VDC working power supply to modules in the slot, with built-in overcurrent and short-circuit protection.
