Functional Features Provides 8‑channel stable 4‑20 mA analog current output for field actuators. High‑precision 16‑bit D/A conversion guarantees output control accuracy. Group‑wise galvanic isolation blocks field‑side electrical interference impact on DCS system. Hardware short‑circuit protection for each output channel. Front‑panel LED indicators display module power‑on, running and fault alarm status. Matched detachable terminal unit simplifies field wiring and module replacement. All channel parameters configured via Control Builder M software without hardware jumpers. Full mechanical and electrical compatibility with S800 series rack hardware.
Application Scenarios Petrochemical and chemical plant analog regulating valve control cabinets. Power plant auxiliary process control output systems. Metallurgical and water‑treatment industry actuator control projects. AC800M DCS system spare‑part overhaul and replacement work.
Installation Requirements Insert AO910 module into designated slot of S800 standard rack and install supporting terminal unit. Complete cabinet protective earthing strictly following official system grounding specifications. Field actuator wiring adopts shielded twisted‑pair cables. Separate signal cables and high‑power power cables. Verify field actuator load impedance does not exceed 750 Ω per channel before power‑on. Reserve cabinet internal ventilation space around module for heat dissipation. Tighten terminal unit screws to manufacturer‑recommended torque values.
