ABB LPS01 LVDT Position Slave Module

Overview

Configured for linear displacement signal conditioning in Bailey Controls Infi 90 I/O architecture, the ABB LPS01 (LPS01 LVDT Position Slave Module) provides direct electrical interface conversion for LVDT-based position measurement within distributed control backplane systems.

Hardware Specifications

Backplane Bus Communication and I/O Density Scaling

The ABB LPS01 interfaces through the Infi 90 backplane architecture, where module-level data exchange is executed via deterministic rack communication cycles. Slot-based addressing enables fixed-latency transfer of LVDT-derived position signals into the controller dataset. I/O density scaling is constrained by chassis configuration, with module timing synchronized to system scan execution. Firmware and hardware revision alignment is required to maintain backplane communication integrity during module replacement or system expansion.

Frequently Asked Questions

Q: Can the LPS01 module be hot-swapped during system operation?
A: Hot-swap capability depends on the Infi 90 chassis implementation. Electrical isolation must be verified before insertion or removal to prevent backplane transient disturbance.

Q: What is the backplane load impact of the LPS01 module?
A: The module draws power directly from the rack backplane. Load distribution is managed at chassis level; slot power budgeting must be observed to avoid bus undervoltage conditions.

Q: Does the module require firmware alignment with controller processors?
A: Compatibility is dependent on Infi 90 system revision matching. Mixed firmware generations may result in communication initialization faults.

Field Installation Guidelines

The LPS01 module must be installed into a compatible Infi 90 rack with system power isolated. Edge connector alignment must be maintained to avoid pin deformation during insertion. Shielded cabling for LVDT input should be terminated with single-point grounding to minimize signal loop interference. Mechanical seating should be verified by full backplane engagement without forced insertion. Module replacement should follow static discharge control procedures and chassis-specific maintenance sequencing.
