Technical Specifications Rack back‑plane bus connector, multi‑channel field signal screw‑type terminals, module locking structure. Working power and signal power supplied by rack back‑plane. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%.
Functional Features Provides installation base for corresponding I/O module. Realizes electrical connection between I/O module and rack back‑plane bus. Provides abundant screw‑type terminals for field sensor and actuator wiring. Supports replacing upper‑position I/O module without disconnecting field cables.
Application Scenarios Spare terminal base for ABB DCS I/O module. Widely used in process industry control cabinet signal wiring.
Performance Parameters Stable multi‑channel signal transmission performance. Reliable mechanical locking and connection characteristic.
Material Composition Flame‑retardant plastic base housing. Multilayer glass‑fiber epoxy printed circuit board. Rack back‑plane plug‑in connector, field signal screw terminals and module locking mechanical parts.
Structural Characteristics Front panel arranges multi‑group field signal screw wiring terminals. Upper‑part clamping structure is used for installing I/O module.
Working Principle TB810 is inserted into control rack slot and connects to back‑plane bus. Field signal connects to screw terminals of base. After I/O module is installed on base, signal completes bidirectional transmission between field side and rack back‑plane bus through base internal circuit.
Installation Requirements Install matched I/O module and lock. Connect field signal cable to front‑panel screw terminals.
Usage Notes Must use matched I/O module. Tighten terminal screws to avoid poor contact.
