Users can configure software-selectable filter time constants(10 ms to 10 s)per channel via DNA Engineering Tool,allowing fine-tuning for fast-response control loops(e.g.,pressure)versus noise-prone slow processes(e.g.,temperature in EMI-heavy areas).

Application Cases and Industry Value

In a biomass power plant retrofit project,the VALMET A413052 was deployed across 12 I/O cabinets to replace obsolete 8-channel analog cards.The upgrade doubled I/O density,cut cabinet count by 40%,and enabled full HART-based predictive maintenance on all field transmitters.Within six months,maintenance teams used HART data from the VALMET A413052 to preemptively replace three failing pressure sensors before they caused combustion instability—avoiding an estimated$220,000 in potential downtime losses.

Another case involved a tissue paper machine where moisture profile control was hampered by noisy analog signals from infrared scanners.After installing the VALMET A413052,the improved signal fidelity allowed tighter control of the drying section,reducing steam consumption by 4.3%and increasing production yield by 2.1%—translating to over€350,000 in annual savings.

Installation,Maintenance,and Full-Cycle Support

Installation of the VALMET A413052 follows standard DNA I/O practices:mount onto an A41x-series backplane,connect shielded twisted-pair cables to the terminal block(A411011 recommended),and ensure proper grounding of cable shields at one end only to avoid ground loops.The module supports hot insertion in non-redundant systems,minimizing process interruption during replacements.

Maintenance is simplified through Valmet DNA’s integrated diagnostics:any deviation—such as a 4–20 mA loop open or signal saturation—is immediately visible in the control room with channel-level granularity.Routine verification can be performed remotely using simulated inputs via the engineering workstation,eliminating manual multimeter checks.Firmware and calibration data are stored onboard,ensuring consistent performance after module swaps.
