Hardware Specifications

Backplane Bus Communication Velocity & Digital Input Processing

The Allen-Bradley 80190-380-01-R digital input module conditions 24 VDC discrete field signals across 8 independent channels, operating with a low current draw of 5 mA per channel. Utilizing high backplane bus communication velocity across Allen-Bradley PLC backplanes, the board transfers digitized input states directly to the main processor without system scan delays. Integrated signal conditioning circuitry suppresses noise spikes and provides clean state detection for high-speed industrial automation control loops.

Frequently Asked Questions

Q: How is the 80190-380-01-R board powered within the host system enclosure?

A: Logic operating power is supplied through the internal system backplane, while digital input channels monitor external 24 VDC field signals drawing 5 mA per active channel.

Q: What mounting precautions should be taken during installation of the board?

A: The circuit board must be fastened to non-conductive standoffs inside the rack assembly, ensuring mounting screws establish proper grounding contact with chassis earth points.

Q: Can the 80190-380-01-R module be inserted while the backplane is powered?

A: No, main control power must be completely switched off before installing or removing the board to prevent voltage spikes across the internal backplane bus.

Field Installation Guidelines

1. De-energize all primary supply lines and control power circuits feeding the host PLC rack before servicing.
2. Put on an anti-static wrist strap connected to a verified earth ground terminal.
3. Position the 80190-380-01-R PCB onto the designated sub-chassis mounting standoffs.
4. Fasten all securing screws firmly to ensure reliable mechanical retention and proper earth grounding continuity.
5. Connect external 24 VDC input field wiring to the channel terminals, ensuring correct polarity and clean cable routing away from AC power lines.
