Valmet has introduced the IOP312, an isolated high-level analog input (HLAI) module designed for the Valmet DNA (formerly Metso DNA) distributed control system. The module provides isolated 4–20 mA current signal acquisition for precise process measurement in industrial applications Volzaplcix auto.
Part of the IOP 300-series I/O processing family, the IOP312 delivers high-precision analog input handling for field transmitters and process instruments, with channel isolation to protect the control system from field-side interference and ground loops Volzaplcix auto.
Key Features
- Isolated analog inputs — channel-level isolation for reliable signal integrity in noisy plant environments
- 4–20 mA signal handling — standard process transmitter interface for flow, pressure, level, and temperature loops
- Valmet DNA integration — native plug-in module for DNA/maxDNA I/O racks
- High precision — designed for accurate measurement in continuous process control
- Proven in service — widely deployed in pulp and paper machine control applicationsVolza
Target Applications
- Pulp and paper making machine control
- Process measurement loops — flow, pressure, level, and temperature transmitters
- Valmet DNA / maxDNA distributed control systems
- I/O expansion and module replacement for DNA control cabinets
The IOP312 is available as a brand-new or refurbished unit with warranty support. For pricing, lead time, or technical consultation, contact our sales team directly.
