Description
ABB TU818
Technical Specifications:
- System: ABB S800 I/O
- Function: Analog Signal Termination
- Module Compatibility: S800 Analog Input Modules
Functional Features:
- Signal Integrity: Designed to minimize noise pickup for sensitive analog signals.
- Shield Termination: Dedicated grounding points for cable shield management.
- Hot-Swappable Support: Allows module replacement without disrupting the field wiring or backplane power.
Application Scenarios:
Process control environments requiring accurate acquisition of 4-20 mA, 0-10 V, or thermocouple signals.
Performance Parameters:
- Channel Capacity: Supports standard 8 or 16-channel analog input modules.
- Dielectric Strength: High isolation between field side and backplane.
Material Composition:
Industrial-grade PCB with precision gold-plated contacts and robust screw terminal blocks.
Structural Features:
Compact design with color-coded terminals and integrated DIN-rail mounting clips.
Working Principle:
Routes low-level analog signals from field transmitters to the input module while providing a solid ground reference for shielding to reject electromagnetic interference.
Installation Requirements:
Use shielded twisted-pair cables for all analog connections. Keep analog wiring separate from high-voltage power cables.
Usage Precautions:
Verify the module alignment before insertion. Ensure all shield connections are tight to prevent ground loops.
