Valmet D201190L AO4H 4-channel analog output module
D201190L AO4H is a 4-channel analog output module of Valmet DCS system. D201190L receives digital control instructions issued by the controller, converts them into standard analog signals, and outputs them to on-site control valves, frequency converters, and other actuators to achieve continuous adjustment of process circuits such as valve opening and equipment speed. It is the core unit of the control system for outputting control signals.

Brand Introduction：
Valmet is headquartered in Finland and its automation business was formerly under Metso. In 2013, Metso’s automation business was merged into Valmet and it is a leading supplier of process industrial equipment and automation solutions for the global pulp and paper, energy, biomass, mining, and building materials industries. Its main products include complete production lines, DCS automation systems, field instruments, valves, analytical instruments, and full lifecycle spare parts and maintenance services.
Core automation products:
Valmet DNA Distributed Control System (DCS) is the main process control system of Valmet, including the old IOP series I/O and the new generation ACN series I/O hardware (D201435L CXW controller D201134L AI8C、D201136L DI16C、D201126L DI8P、D201129L DO8P、D201436L DO16C Etc.)
- Hardware: ACN rack, redundant controller module, analog input/output, digital input/output I/O card, bus communication module; Support module hot plugging, channel level fault diagnosis, wide temperature industrial working conditions, support 1:1 controller redundancy, ensuring uninterrupted continuous production.
- Software: Process control software, human-machine interface HMI, historical trends, alarm management, advanced process control APC, equipment status monitoring, asset operation and maintenance management software.
- New generation platform: DNAe , web architecture DCS, strengthened network security, suitable for key process devices such as power plants and ships.
Product features
- 4 independent analog output channels, supporting current and voltage signal types, can directly drive regulating valves and variable frequency actuators.
- Channel isolation design effectively isolates on-site interference, protects the main control system, and enhances the stability of the control circuit.
- Each channel is equipped with independent status LED indicator lights, which can visually view module operation, faults, and output status, facilitating on-site troubleshooting.
- Modular plug-in structure, supporting quick disassembly and assembly of racks, with short downtime for replacing spare parts.
- Built in short-circuit protection and overload protection, which can protect the module body in case of on-site circuit faults.
- Native compatibility with Valmet D series controllers, simple configuration, and adaptability to the entire Metso old DCS system.
