Quality Control Process
Every replacement module undergoes strict signal injection testing. We apply precision reference temperatures using calibrated RTD simulators. Output linearity must remain within ±1% tolerance. Next, we verify thermocouple cold-junction compensation accuracy. Drift exceeding factory specs triggers immediate rejection. We then inspect the backplane edge connector for bent pins. Oxidation or physical damage causes intermittent data loss. Finally, we validate internal diagnostic registers. All units ship in anti-static shielding.
Replacement Pitfall Guide
❗ Verify Sensor Type Configuration. This module supports both RTD and TC inputs. Ensure the software configuration matches your physical wiring. Applying an RTD signal to a TC-configured channel yields completely false readings.
❗ Check Wire Termination. Temperature signals are highly susceptible to noise. Verify all shielded twisted-pair wiring is properly terminated. Ground loops will inject false temperature spikes into your trending data.
❗ Inspect Cold-Junction Compensation. For thermocouple inputs, ensure the module’s internal CJC is functioning. A failed CJC causes ambient temperature shifts to appear as process temperature changes.
❗ Match the Ordering Code. The 136711-01 suffix defines specific terminal and barrier configurations. Swapping to a different suffix may alter input impedance. Always verify the exact 136711-01 specification before installation.
Keep these in mind and you’ll cut 90% of rework time.
