TRICONEX 4119A safety analog output module

The Triconex 4119A is a safety analog output module from the Triconex (now part of Schneider Electric) Tricon safety instrumented system (SIS) family. Below are its key technical parameters:

Triconex 4119A Analog Output Module Specifications:

1. Channels:

• • 8 isolated analog output channels (configurable per channel).

2. Output Signal Type:

• • 4-20 mA (current output, default)
  • 0-20 mA (optional)
  • Voltage output (optional, if supported)

3. Resolution:

• • 16-bit (high precision)

4. Accuracy:

• • Typically ±0.1% of full scale (for current output).

5. Isolation:

• • Channel-to-channel isolation (prevents cross-talk/interference).
  • Isolation between field side and system side (enhanced safety).

6. Load Resistance:

• • Maximum 750 Ω (for 4-20 mA current output).

7. Update Rate:

• • Typically 10 ms per channel (varies based on configuration).

8. Redundancy Support:

• • Supports TMR (Triple Modular Redundancy) for fault tolerance.

9. Communication Interface:

• • Interfaces with the Tricon main processor via the backplane.

10. Power Supply:

• • Module power: Typically 5V DC (from the Tricon chassis).
  • Field power: Requires an external 24V DC power supply for outputs.

11. Diagnostics & Safety Features:

• • Open-circuit detection (for current outputs).
  • Short-circuit protection.
  • Online module replacement (hot-swappable in redundant systems).

12. Certifications & Compliance:

• • IEC 61508 (Functional Safety).
  • SIL 3 (Safety Integrity Level) capable.
  • CE, ATEX (for hazardous environments, if applicable).

13. Operating Temperature:

• • -40°C to +70°C (industrial-grade).

14. Mounting:

• • Installed in a Tricon V9/V10/V11 chassis.

Applications:

• Safety-critical analog control in oil & gas, chemical plants, power generation.
• Emergency shutdown systems (ESD).
• Fire & gas safety systems.
