Description
Product Overview
The 3805H Analog Output Module from Triconex delivers precise current control for safety-critical industrial systems. Designed for Triconex platforms, this 8-channel module outputs 4–20mA signals with +6% overrange capability, supporting high-resolution process control.
Each channel in the 3805H maintains independent isolation and calibration, allowing flexible configuration across complex automation environments. Its 12-bit resolution ensures fine signal granularity, while the module’s <0.25% FSR accuracy supports demanding applications in oil, gas, and chemical sectors.
Engineers rely on the 3805H for its Triple Modular Redundant (TMR) architecture, which automatically compensates for component failures. The module operates reliably from -40°C to +70°C, maintaining performance in extreme climates from arctic zones to desert installations.
Its DC-coupled current loops and hazardous area compliance make the 3805H ideal for emergency shutdown systems and safety instrumented systems (SIS). The module’s robust design reflects Schneider Electric’s commitment to fault-tolerant control and industrial safety.
