Design and Energy Storage
This unit stores no significant electrical energy internally. A heavy-duty copper bus bar distributes power evenly. Each slot has individual overcurrent protection for safety. The metal chassis provides excellent mechanical rigidity. Furthermore, this mounting unit includes a ground terminal for system earthing.
Installation and Connectivity
You can mount this unit on a panel or in a 19-inch rack. It accepts I/O modules by sliding them into guided slots. A main power terminal connects to an external 24V supply. Consequently, you complete the installation within a few minutes. Finally, labeling strips identify each slot for easy maintenance.
Performance and Power Distribution
This unit consumes no power on its own. Its 15A bus capacity supports up to eight fully loaded modules. Thus, you get reliable power delivery for large I/O configurations. Each slot receives filtered and regulated backplane voltages. The unit also includes reverse polarity protection on the input terminals.
Typical Applications
Use this power mounting unit for housing INFI 90 I/O modules. It also excels at organizing field terminations in control cabinets. Many plants select this unit for turbine control system upgrades. The compact design saves valuable enclosure space effectively. Finally, removable front covers allow access without powering down.
