Key Features

12‑Channel High‑Density Design: Delivers 12 isolated analog outputs in a single module, reducing cabinet space and wiring complexity for multi‑loop control systems.

Dual Output Mode Support: Jumper‑selectable 4–20 mA current or 0–10 VDC voltage output eliminates the need for multiple module variants for different field devices.

High Precision & Stability: 12‑bit resolution with ±0.1% FS accuracy ensures consistent, reliable control for critical process loops.

Full Redundancy Compatibility: Works with the MU‑TAOX12 FTA to support 1:1 redundant AO module switching, enabling automatic failover on fault for maximum system availability.

Enhanced Electrical Isolation: 2,500 Vrms isolation protects the controller and backplane from field transients, ground loops, and electrical noise in harsh industrial environments.

Comprehensive LED Diagnostics: Front‑panel LEDs for power status, communication health, per‑channel output status, fault alarms, and redundancy mode for quick on‑site troubleshooting.

Hot‑Swappable Design: Can be installed or replaced without shutting down the entire DCS system, minimizing unplanned downtime.

Conformal Coated PCB: Protects the circuit board from dust, moisture, vibration, and corrosion in extreme industrial field conditions.

Global Compliance: UL, CE, and ISO certified for worldwide industrial process control applications.
