Emerson VE4002S2T2B8 Control Module
Emerson VE4002S2T2B8 is a key Discrete Output Plus Card in the Emerson DeltaV series control system, mainly used to send digital control signals to actuators such as valves, solenoid valves, relays, etc. on site.

1. Core functions and positioning
Discrete output core: This module is specifically designed to control 32 digital outputs (such as switch signals) and belongs to the “Plus” series in the DeltaV series, supporting high-end wiring.
Electrical characteristics: The output voltage is 24V DC, belonging to the “Potential Contact” type, which can directly drive field devices (such as valve solenoid coils).
Communication compatibility: As one of the core modules of the DeltaV system, it can seamlessly integrate with upper computer controllers (such as VE3008, VE3009) through DeltaV communication protocols (such as HART, Foundation Fieldbus) to achieve real-time data acquisition and control.
