Description
Emerson VE3008
Technical Specifications: Working voltage 24VDC. 8 digital input channels. Input signal type dry contact or 24VDC active signal. Operating temperature ‑40°C ~ +70°C. SIL2 safety certification.
Functional Features: 8 independent digital input channels. Channel fault detection, wire break detection. Hot‑swap support. LED indicator for each channel status. Built‑in channel overvoltage protection.
Application Scenarios: Plant emergency shutdown system, fire and gas detection system, safety valve feedback monitoring, emergency stop circuit monitoring, compressor safety interlock.
Performance Parameters: Channel sampling cycle 20ms. Wire break detection accuracy 100%. MTBF 460000 hours.
Material Composition: FR‑4 flame retardant PCB. UL94‑V0 plastic housing. Gold‑plated terminal connectors, signal isolation chips, surge protection components.
Structural Features: Rack plug‑in module for DeltaV SIS rack. Front panel with independent LED indicator for each channel. Terminal block connects field wiring.
Working Principle: Each input channel detects field contact status or 24V digital signal. The module performs wire break diagnosis for each channel. Valid digital signals are converted to digital data and sent to SIS controller via backplane bus. Fault information is uploaded when channel wiring fault occurs.
Installation Requirements: Install in DeltaV SIS rack. Connect field safety wiring to terminal block. Torque terminals to specified value. Ensure cabinet grounding.
Usage Notes: Field wiring must comply with explosion‑proof standard in hazardous zone. Do not exceed rated input voltage. Regularly check channel wiring integrity.
