Backplane Bus Communication Velocity & Power Distribution
The 80026-518-01 DC switching power supply converts a 56 VDC nominal bus input into 7 isolated secondary DC voltage outputs (5 VDC, 15 VDC, and 24 VDC) to drive internal backplane logic and external field instrument loops. By delivering low-ripple 5 VDC power to backplane bus transceivers, the module stabilizes backplane bus communication velocity and supports firmware flash compatibility across installed I/O racks. Onboard pulse-width modulation (PWM) switching topology maintains high energy efficiency and thermal dissipation control across extended operating temperature ranges from -40 deg C to 70 deg C without degrading power density scaling.
Frequently Asked Questions
Q: What are the specific DC output voltage levels generated by the 80026-518-01 supply module?
A: The module generates 7 regulated DC power rails configured at 5 VDC for backplane control logic, 15 VDC for analog signal conditioning, and 24 VDC for discrete I/O loop power, with a total continuous current limit of 5 A.
Q: Is the 80026-518-01 power supply designed for hot-swapping under energized input conditions?
A: No. The primary 56 VDC supply power must be fully disconnected and isolated prior to inserting or removing the power supply module from the rack chassis to prevent arcing and connector pin degradation.
Field Installation Guidelines
- Isolate and de-energize the primary 56 VDC input power feed before inserting the power supply into the control chassis.
- Align the module card edges with the internal chassis slots and slide the assembly back until the multi-pin connector seats completely into the backplane frame.
- Secure all mechanical retaining screws on the front panel to ensure low-resistance frame grounding and mechanical stability under high-vibration conditions.
- Verify that field wiring for 24 VDC external loops is routed separately from high-noise AC switching lines to minimize induced electromagnetic interference.
- Ensure cabinet convection pathways remain unobstructed to support passive heat dissipation across the wide -40 deg C to 70 deg C operating thermal envelope.
