System compatibility

cFP-SG-140 belongs to NI Compact FieldPoint platform.It works with cFP series backplanes and real-time controllers,supported by LabVIEW and NI FieldPoint drivers,widely used for load cell,torque and structural strain monitoring in industrial systems.It is spare part for legacy automation equipment overhaul.

Function

cFP-SG-140 is hot-swappable 8-channel strain gauge bridge input module for Compact FieldPoint system.It acquires signals from strain gauges,load cells and pressure transducers.Pulsed excitation reduces sensor self-heating,onboard bridge completion and noise filtering,supports hot swap replacement without system shutdown.

Installation

Insert cFP-SG-140 into Compact FieldPoint backplane,tighten captive mounting screws.Wire strain gauge or load cell bridge sensors to front screw terminals.Take ESD protection before installation,supports hot swap operation.

Interface

‑Front screw terminal block for bridge sensor wiring

‑Compact FieldPoint backplane connector

‑POWER,READY and module status LED indicators

Feature

cFP-SG-140 classic NI strain gauge bridge measurement module.Typical faults:terminal block corrosion,signal conditioning circuit damage,backplane pin oxidation.Inspect terminals and test sensor reading before replacement.

Diagnostic

Fault phenomenon:unstable strain reading,zero drift,no signal output.Check wiring and terminal tightness,sensor bridge integrity,verify backplane communication and module status LED.

Product Brief

cFP-SG-140 is NI Compact FieldPoint 8-channel 16-bit strain gauge input module for full/half/quarter bridge transducers,with selectable excitation voltage,2300V transient isolation,hot swappable,used for industrial force,weight and structural strain measurement.Mainly used for maintenance and replacement of old industrial automation equipment.ESD protection must be followed during handling.
