Emerson VE4002S1T2B6 High-Density Discrete Output Card
The Emerson VE4002S1T2B6 delivers robust 32-channel discrete output control for mission-critical DeltaV distributed control systems. Engineered with dual 16-channel mass termination architecture, this high-side switching module provides reliable 24VDC output signals for solenoid valves, motor starters, and field actuators across process industries.
Technical Specifications
- Output Channels: 32 discrete outputs (dual 16-channel groups)
- Voltage Rating: 24VDC high-side switching
- Termination: Two 40-pin mass termination blocks (MTB)
- Current Capacity: 0.5A per channel, short-circuit protected
- Isolation: Channel-to-channel and channel-to-backplane optical isolation
- Diagnostics: Per-channel fault detection with LED status indicators
- Operating Temperature: 0°C to 60°C (32°F to 140°F)
- Compliance: CE, UL, CSA, ATEX Zone 2 certified
Industrial Applications
Deploy the VE4002S1T2B6 in demanding automation environments requiring high-density digital control:
- Petrochemical Processing: Control pneumatic valve actuators and emergency shutdown devices in refinery units
- Power Generation: Manage turbine auxiliary systems, boiler feedwater controls, and cooling tower operations
- Pharmaceutical Manufacturing: Regulate clean-in-place (CIP) valve sequencing and batch reactor interlocks
- Water Treatment: Operate chemical dosing pumps, filtration backwash cycles, and clarifier mechanisms
System Integration Benefits
This discrete output card integrates seamlessly into DeltaV I/O subsystems with hot-swappable carrier design. The dual mass termination blocks eliminate individual wire connections, reducing installation time by 60% compared to traditional terminal strip wiring. Built-in surge protection and EMI filtering ensure signal integrity in electrically noisy industrial environments.
Advanced Diagnostics & Maintenance
Real-time channel diagnostics detect open-circuit, short-circuit, and overload conditions with millisecond response. The DeltaV control system provides predictive maintenance alerts based on output switching frequency and thermal stress analysis, minimizing unplanned downtime.
