Product Short Description
Product Introduction:
Metso D201129 is an 8-channel digital output module from the DO8P series, manufactured by Metso (now Valmet). As a core execution component of the Metso DNA DCS distributed control system, this module receives digital control signals from PLC or control systems and converts them into switching signals capable of driving relays, solenoid valves, indicator lights, and other field actuators.
