Valmet D202593 Product Description
I. Basic Information
Brand: Valmet (formerly Metso Automation)
Part Number: D202593
Product Type: Terminal Base for Metso/Valmet DCS System I/O Modules (Terminal Base)
Compatible System: Valmet DNA DCS Control System (widely used in pulp and paper, energy, power plants, biomass thermal power, chemical industries)
Installation Method: DIN rail installation, used for on-site I/O card front connection, achieving on-site cable isolation and transfer for the purpose of on-site wiring and card-free line replacement and maintenance.
Integrated signal lightning protection, filtering, and line short-circuit protection functions, which can suppress on-site surges and electromagnetic interference, protecting the main control I/O card from being damaged by on-site faults.
Built-in channel fault loop detection terminals, supporting card breakage and short-circuit diagnostic signals being uploaded to the DCS system.
Core Function Description
As a wiring base for various analog and digital I/O cards, on-site cables are crimped onto this terminal base, and the rear end is connected to the DCS I/O module through connectors, facilitating on-site pre-wiring and card-free line replacement and maintenance for the cards.
Integrated signal lightning protection, filtering, and line short-circuit protection functions, which can suppress on-site surges and electromagnetic interference, protecting the main control I/O card from being damaged by on-site faults.
Built-in channel fault loop detection terminals, supporting card breakage and short-circuit diagnostic signals being uploaded to the DCS system.
Hardware Specifications
Standard industrial terminal layout, with screw-fastened wiring terminals, suitable for multi-core shielded control cables;
With plug-in connectors, allowing for quick disassembly and assembly of I/O modules, and no need to remove the on-site wiring for card replacement and maintenance;
Integrated electrical isolation circuit, with a withstand voltage of up to 1500VAC, resistant to ground loop interference;
Operating Environment: -20℃ to +70℃, protection level IP20, DIN rail installation in the cabinet;
Power supply is fed by the I/O backplane, supporting 24VDC industrial conventional instrument circuit power supply.
Typical Compatible Cards
Mainly used to support Valmet DNA series AI, AO, DI, DO type I/O cards, common combinations include:
Analog input card, analog output card (4-20mA, RTD, thermocouple signals)
Switch input/output digital card
Mostly used for DCS measurement points collection and control output in pulp and paper mills, alkali recovery, boilers, steam turbines.
Main Application Scenarios
Valmet DNA DCS control cabinet wiring transfer for the entire pulp and paper plant;
DCS measurement point terminal transfer for biomass power plants, waste incineration power plants, thermal power plants, boiler side, turbine side;
Signal isolation transfer for on-site instrument signals in metallurgy and chemical process automation systems;
Replacement of old Metso automation systems and control cabinet renovation projects.
