Triconex 8312 Power Supply Module

The Triconex 8312, also cataloged as the 8312 Power Supply Module, operates as a dedicated hardware component for uninterruptible power regulation within Triconex safety instrumented systems.

Hardware Specifications

Triple Modular Redundancy and Fail-Safe Power Execution

The module architecture supports high-availability safety instrumented functions through galvanically isolated power conversion and robust internal energy storage. Utilizing an integrated backup string of four 3.7V rechargeable lithium-ion cells delivering 14.8V, the unit guarantees a minimum output hold time of 20 ms during primary AC line dropouts. This ensures uninterrupted logic execution across redundant chassis architectures, while the internal 2.5A time-delay fuse protects downstream backplane circuits against overcurrent conditions and transient power spikes.

Frequently Asked Questions

Q: What is the primary input voltage range for the Triconex 8312 module?

A: The module operates on a nominal input of 230 VAC, with an accepted operational range of 185 to 285 VAC at 47 to 63 Hz.

Q: What backup energy storage mechanism is integrated into the power supply?

A: The unit incorporates an internal 14.8V battery pack consisting of four 3.7V rechargeable lithium-ion cells to provide a minimum output hold time of 20 ms.

Q: What are the fuse specifications for protecting this power supply module?

A: The module is protected by a 2.5 amp, time-delay fuse rated for industrial safety applications.

Field Installation Guidelines

• Verify that incoming 230 VAC supply lines are fully isolated and locked out before mounting or wiring the power supply module into the safety chassis.

• Ensure proper cabinet ventilation and spacing around the module dimensions (52 mm x 46 mm x 19 mm) to maintain optimal thermal dissipation during continuous operation.

• Confirm that the protective earth ground and shield terminals are securely fastened to prevent electromagnetic interference and ground loops.

• Inspect the internal lithium-ion battery status and input fuse rating prior to initial system energization and safety loop commissioning.
