Technical Specifications Part Number: 3BSE040662R1 Operating Supply Voltage: 24 VDC ±10% Number of Input Channels: 8 independent RTD channels Supported Sensors: Pt100, Pt1000, Ni100, Ni1000, Cu50 Wiring Modes: 2‑wire, 3‑wire, 4‑wire A/D Resolution: 16‑bit Isolation: Group galvanic isolation Operating Temperature: 0 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mounting Type: S800 rack plug‑in Protection Class: IP20 Certifications: CE

Functional Features High‑precision acquisition for multiple types of resistance temperature detectors. Supports three mainstream field sensor wiring modes. High‑accuracy resistance measurement algorithm reduces cable resistance error impact. Continuous sensor loop open‑circuit and short‑circuit fault diagnosis. Group‑wise galvanic isolation protects control system from field‑side interference. Front‑panel LED indicators for power, operation and fault status. Parameter configuration via Control Builder M software without hardware jumpers. Compatible with S800 rack and series supporting terminal units.

Application Scenarios High‑precision temperature measurement in petrochemical process plants. Power plant turbine and boiler critical point temperature monitoring. Pharmaceutical industry precise thermal process parameter collection. AC800M / 800xA DCS system upgrade and spare‑part replacement projects.

Installation Requirements Insert AI830A module into designated S800 rack slot and install supporting terminal unit. Carry out cabinet protective earthing strictly according to system grounding specifications. Field RTD wiring uses shielded twisted‑pair cables. Keep signal cables separated from high‑power cables. Confirm sensor wiring mode matches software channel configuration before power‑on. Reserve sufficient cabinet ventilation space around the module. Tighten terminal unit screws to manufacturer‑specified torque values. Maintain ambient operating environment within rated temperature and humidity ranges without condensation.
