Description
ABB TU516B9 1SAP212000R0001
Technical Specifications:
- Order Code: 1SAP212000R0001.
- Compatibility: Designed for S800 series I/O modules.
- Power Distribution: Distributes 24V DC field power to the plugged-in module.
- Wiring Type: Spring-clamp or screw terminals (depending on variant).
Functional Features:
- Plug-and-Play: Allows hot-swapping of I/O modules without disconnecting field wiring.
- Organized Wiring: Clearly labeled terminals for easy identification and maintenance.
- Shield Connection: Integrated shield clamp for proper cable grounding.
- Diagnostic Access: Provides test points for field signal verification.
Application Scenarios:
- Field termination for distributed I/O in process industries.
- Panel-mounted I/O for discrete control applications.
- Retrofit and expansion of existing S800 systems.
Material Composition & Structural Characteristics:
- Housing: Durable industrial plastic with DIN rail mounting.
- Terminals: High-reliability spring-clamp terminals for solid and stranded wire.
- Labeling: Integrated label strip for wire identification.
Working Principle:
The TU516B9 acts as a passive interface between field wiring and the active I/O module. Field wires connect to the base unit terminals, and the I/O module plugs onto the base unit, making electrical contact through precision connectors. Power and signals are routed through the base unit to the module.
Installation Requirements:
- Mount on a standard 35mm DIN rail.
- Strip wire to the correct length and insert into the spring-clamp terminal.
- Attach the cable shield to the integrated shield clamp.
Usage Precautions:
- Ensure the I/O module is fully seated and locked onto the base unit.
- Do not exceed the terminal wire size or current rating.
