Technical Specifications Multi‑channel screw‑type signal terminals, auxiliary power distribution terminals. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Protection grade IP20. Meets S800 I/O system mechanical and electrical specification.
Functional Features Provides field‑side wiring interface for analog and digital I/O signal loops. Realizes bidirectional signal transmission between field cables and inserted I/O modules. Completes back‑plane bus signal routing. Equipped with mechanical locking structure for I/O modules. Supports hot‑swap operation under system allowed state.
Application Scenarios Used as supporting termination base for S800 I/O modules in power plant, petrochemical and metallurgical DCS system. Applied for new project construction and field spare‑part replacement.
Performance Parameters Stable low‑resistance contact at terminal and slot contact points. Mechanical locking structure resists cabinet vibration. Signal transmission keeps stable under long‑term continuous operation.
Material Composition Glass‑fiber epoxy printed circuit board. Reinforced flame‑retardant plastic housing. Copper‑alloy screw wiring terminals. Back‑plane plug‑in contact pieces. Plastic module locking buckle assembly.
Structural Characteristics Standard rack‑mount base unit structure. Front section arranges field signal wiring terminals. Upper slot is for inserting matched I/O module. Rear side connects rack back‑plane bus. Weight approximately 0.39 kilogram.
Working Principle Field analog or digital signals connect to screw terminals of TU810V1. Signals pass internal circuit board and transmit to plugged I/O module through slot contact points.
Installation Requirements Mount TU810V1 base onto designated DCS rack position and fasten fixing screws. Complete field signal cable wiring strictly according to engineering drawing. Ensure cabinet protective grounding. Insert compatible I/O module into slot and engage locking buckle.
Usage Notes Prevent metal debris and conductive dust from entering terminal area. Check terminal tightening torque periodically. Confirm I/O module model is compatible with TU810V1 base. Keep cabinet internal environment away from corrosive gas.
