System compatibility

cFP-TC-125 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 furnace,pipe and equipment temperature monitoring.It is spare part for legacy automation equipment overhaul.

Function

cFP-TC-125 is hot-swappable 8-channel thermocouple input module for Compact FieldPoint system.It supports 8 common thermocouple types and millivolt signal acquisition,with built-in cold junction compensation and sensor linearization.Break wire detection helps diagnose faulty probes,supports hot swap replacement without system shutdown.

Installation

Insert cFP-TC-125 into Compact FieldPoint backplane,tighten captive mounting screws.Wire thermocouple cables to front screw terminals.Take ESD protection before installation,supports hot swap operation.

Interface

‑Front screw terminal block for thermocouple sensor wiring

‑Compact FieldPoint backplane connector

‑POWER,READY and module fault LED indicators

Feature

cFP-TC-125 classic NI thermocouple temperature I/O module.Typical faults:terminal block corrosion,ADC circuit damage,backplane pin oxidation.Inspect terminals and test temperature reading before replacement.

Diagnostic

Fault phenomenon:temperature reading drift,intermittent signal,open sensor alarm.Check wiring and terminal tightness,thermocouple probe integrity,verify backplane communication and module status LED.
