ABB CTB810 HN800 Terminal Base Unit

Technical Specifications Model: CTB810 HN800 System Compatibility: ABB HN800 control‑system functional modules Power Supply: 24 V DC power‑supply input, distributes power to plugged‑in functional modules Interface: Internal backplane bus for HN800 module communication, multi‑group screw‑type field‑signal terminal blocks Mounting Type: Standard DIN‑rail mounting Operating Temperature: ‑25 ℃ to +70 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE

Functional Features Provides mechanical plug‑in installation base for HN800 series processor and I/O functional modules. Distributes 24 V DC working power‑supply to each plugged‑in functional module. Routes internal backplane bus signal for data interaction between plugged‑in modules. Centralizes field‑site input‑output signal wiring to front‑side screw‑type terminal blocks. Supports hot‑swap of upper functional‑module without disconnecting field‑side wiring terminals. Each terminal block corresponds to defined signal channel of matched HN800 module. DIN‑rail compact base‑unit structure for convenient cabinet‑internal installation.

Application Scenarios HN800 control‑system terminal base‑unit spare‑part replacement. Power‑plant and industrial‑process control cabinet for installing HN800 series processor and I/O modules. System maintenance‑optimized project requiring functional‑module hot‑swap capability.

Installation Requirements Snap CTB810 HN800 base‑unit onto standard DIN‑rail inside control cabinet and lock back‑side spring‑clip. Connect 24 V DC power‑supply input cable to dedicated power‑supply screw‑type terminals. Connect field‑site input‑output signal cables to corresponding channel screw‑type terminals, tighten terminals to specified torque value. Insert matched HN800 functional‑module into internal socket of CTB810 base‑unit and lock module‑side spring buckle. Complete cabinet protective earthing complying with HN800 system grounding specifications. Separate field‑signal cables and high‑power power cables inside control cabinet. Reserve surrounding ventilation heat‑dissipation space for base‑unit and plugged‑in modules. Ambient operating temperature must keep within ‑25 ℃ ~ +70 ℃ without condensation.
