Metso A413003 Basis Unit DCS Main Base Module

Product Description

The A413003 is a Metso (Valmet) basis unit for the legacy Metso DCS automation system, the core base rack unit for connecting processor, I/O and communication modules. It provides backplane bus, power distribution and signal routing for the whole control rack. It serves as the mechanical and electrical foundation to assemble CPU, analog/digital I/O boards and communication adapters, widely used in pulp & paper, mineral processing and metallurgy plant control systems.

FAQ

Q: What is the relationship between A413003 and other Metso I/O modules?
A: A413003 is the base backplane unit; processor, AI/AO, DI/DO modules plug into its slots to form a complete control rack.

Q: Is A413003 discontinued?
A: Yes, this is legacy Metso DCS hardware, out of original production, only available as surplus, refurbished and tested spare parts.

Q: What is the difference between A413003 and A413004?
A: They are different slot quantity variants of the basis unit, supporting different numbers of I/O modules.

Q: Can it work alone without CPU module?
A: No, it is only a passive/active backplane basis unit, it must match with dedicated processor module to run control logic.
