METSO IOP320 181545 – 8-Channel Analog Output Module | Metso DNA DCS Platform
Engineering Background
The METSO IOP320 (Part No. 181545) is a high-precision 8-channel analog output I/O module designed for the Metso DNA distributed control system platform. Originally engineered for demanding process industries including pulp & paper, power generation, oil & gas, and chemical processing, this module delivers reliable 4–20 mA current loop outputs with optional HART communication capability. It integrates seamlessly into Metso DNA controller cabinets, providing deterministic signal conditioning and galvanic isolation for field instrumentation.
Product Positioning
The IOP320 181545 is the preferred analog output card for engineers maintaining or expanding legacy Metso DNA systems. Its plug-and-play compatibility with existing I/O bus architectures eliminates costly re-engineering, while its robust industrial-grade construction ensures long-term reliability in harsh plant environments. Konmask.com supplies this module as a tested, genuine replacement unit with full traceability documentation.

System Architecture & Signal Flow
The IOP320 181545 mounts on a Metso DNA I/O bus carrier and communicates with the system controller via the proprietary I/O bus backplane. Each of the 8 output channels independently converts a digital setpoint from the controller into a precision 4–20 mA current signal. The HART modem layer superimposes a digital FSK signal on the 4–20 mA loop, enabling bidirectional communication with HART-capable field instruments. Galvanic isolation barriers on each channel prevent common-mode interference from propagating to the controller bus, ensuring signal integrity across long cable runs in electrically noisy plant environments.
