🔌 Power Supply Function
The 8312C supplies regulated DC power to the Tricon system chassis.
In a Tricon architecture, power modules are installed on the left side of the chassis and provide the internal power required by the processor and I/O system.
A redundant power arrangement can improve system availability because the Tricon architecture can use more than one installed power module.
The module is therefore commonly maintained as an important spare part in installations where continuous system operation is required.
🏭 Typical Applications
The TRICONEX 8312C can be used in systems such as:
🔹 Safety Instrumented Systems
🔹 Emergency Shutdown Systems
🔹 Turbine Control Systems
🔹 Oil and Gas Facilities
🔹 Petrochemical Plants
🔹 Refinery Control Systems
🔹 Power Generation Systems
🔹 Process Safety Applications
🔹 Industrial Automation Systems
🔹 Legacy Tricon Control Installations
🛠️ Installation Notes
Before replacing an existing power module, verify the complete model number and input-voltage requirement.
Recommended installation checks include:
- Confirm that the installed system requires the 230 VAC power module version.
- Verify the input voltage is compatible with the module specification.
- Check the chassis type and power-module position.
- Inspect the power terminals and wiring.
- Confirm proper protective grounding.
- Check the condition of the power-module connectors.
- Install the module according to the applicable Tricon system procedure.
- Verify the PASS indicator after startup.
- Check for FAULT, ALARM, TEMP, or BAT LOW indications.
- Confirm normal system operation after replacement.
For redundant systems, follow the site’s approved maintenance procedure before removing or replacing a power module.
⚠️ Important Application Note
The 8312 power module family is designed for 230 VAC input applications. It should not automatically be substituted with another Tricon power module.
Different Tricon power-module versions include:
- 8310 — 120 VAC/VDC power module
- 8311 — 24 VDC power module
- 8312 / 8312C — 230 VAC power module
The input voltage and installation requirements should always be checked before replacement.
