Allen-Bradley 80190-100-01-R Fiber Optic Control Board

The Allen-Bradley 80190-100-01-R, also cataloged as the 80190-100-01-R Fiber Optic Board, operates as a dedicated hardware component for high-voltage isolation, optical signal transmission, and gate drive firing control within PowerFlex 7000 platforms.

Hardware Specifications

Backplane Bus Communication Velocity & Optical Signal Isolation

The Allen-Bradley 80190-100-01-R utilizes fiber optic input and output interfaces to establish galvanic noise immunity between medium-voltage power electronics and low-voltage control processors. Operating with high backplane bus communication velocity, the board converts electrical firing commands into optical pulses sent directly to gate driver modules inside PowerFlex 7000 drive systems. Firmware flash compatibility ensures synchronized deterministic switching control and fault diagnostic feedback execution.

Frequently Asked Questions

Q: What function does the fiber optic interface serve on the 80190-100-01-R board?

A: Fiber optic connections provide complete electrical isolation between high-voltage power components and sensitive control circuits, eliminating noise coupling and protecting control logic from high-voltage transients.

Q: How is physical alignment and connection of optical cables maintained on the board?

A: Fiber optic cables snap directly into dedicated transmitter/receiver optical connectors mounted on the PCB, ensuring low signal loss and secure mechanical engagement.

Q: Can the 80190-100-01-R board be serviced or replaced while the drive is energized?

A: No, main medium-voltage power and control power must be fully isolated and discharged before servicing the board to prevent equipment damage and electrical hazards.

Field Installation Guidelines

1. Disconnect and lock out all medium-voltage AC supply lines and 120/230 VAC control power sources to the PowerFlex 7000 drive enclosure.
2. Verify zero potential on all power buses and wait for internal DC link capacitors to discharge fully.
3. Put on an anti-static wrist strap connected to a verified chassis ground point before opening the control rack.
4. Carefully disconnect fiber optic cables by depressing retaining clips; do not exceed the minimum bend radius of the fiber optic lines.
5. Mount the replacement 80190-100-01-R board onto chassis standoffs, secure with mounting hardware, and reattach optical cables to matching channel ports.
