triconex 8311 Power Module丨 Main/Expansion/RXM
Each Tricon chassis is equipped with two Power Modules—either one is fully capable of running the Tricon at full load and rated temperature. Each Power Module can be replaced online. The Power Modules, located on the left side of the chassis, convert line power to DC power appropriate for all Tricon modules. Terminal strips for system grounding, incoming power and hardwired alarms are located on the lower left corner of the backplane. Incoming power should be rated for a minimum of 240 watts per power supply.
The Power Module alarm contacts are actuated when:
• A module is missing from the system
• The hardware configuration conflicts with the control program’s logical configuration
• A module fails
• A Main Processor detects a system fault
• Primary power to a Power Module fails
• A Power Module has a “Low Battery” or “Over Temperature” warning
