METSO IOP305 16-Channel Common Voltage Analog Input Module

Product Description

The IOP305 is a Metso (Valmet) MaxPAC / Damatic XDi common voltage analog input module, part of the A413 rack I/O series. It collects 0–2.4V voltage signals from field transmitters and sensors, converts analog signals into digital data for the DCS controller. It is a non-isolated common type analog input card, compatible with A413003 basis unit, PDP401 power module, IOP321A AO and IOP334 DI modules. It is widely used for process variable acquisition in pulp & paper and mineral processing plants.

FAQ

Q: What is the difference between IOP301 and IOP305?
A: IOP301 is isolated AI module; IOP305 is common voltage non-isolated AI for 0–2.4V signals.

Q: Which rack is IOP305 compatible with?
A: It fits A413003 basis unit, works with PDP401 power supply module.

Q: Is IOP305 discontinued?
A: Yes, this legacy MaxPAC I/O hardware is end-of-life, supplied as surplus, refurbished and tested spare parts only.

Q: Can IOP305 be mixed with IOP321A and IOP334 in the same rack?
A: Yes, IOP305 (AI), IOP321A (AO) and IOP334 (DI) are common mixed I/O combinations for A413 racks.
