The Emerson DeltaV VE4002S1T1B2, also identified by part number 12P0557X162 and order code KJ3001X1-BG1, is a specialized digital output isolated terminal block. Engineered for the DeltaV distributed control system architecture, this module acts as a secure interface between control logic and field-mounted actuators. It provides eight channels of isolated discrete signaling, specifically designed to maintain signal integrity and electrical protection in high-stakes industrial environments such as chemical processing, oil and gas, and utility power generation.
This module is intended for use in demanding process control applications where electrical isolation is required to protect sensitive controller hardware from field-side transients. It is commonly deployed to drive discrete actuators, relays, and solenoid valves within the DeltaV ecosystem.
