Cold Junction Compensation & Channel-to-Channel Isolation

The module incorporates internal cold junction compensation (CJC) algorithms directly on the analog front-end to correct for ambient thermal drift during thermocouple voltage processing. High-density signal routing utilizes 1500 VDC galvanic isolation between field-side terminal connections and logic backplane lines. This isolation barrier prevents electrical noise, common-mode voltage spikes, and ground loops from compromising 16-bit analog-to-digital converter resolution across all 16 single-ended channels.

Frequently Asked Questions

Q: How does the module process 4-20 mA current inputs without internal shunt resistor thermal wear?

A: Current loops route through precision 250 ohm load resistors located directly on the underlying I/O Termination Assembly (IOTA), converting 4-20 mA currents into 1-5 VDC signals before entering the electronic module.

Q: Can different input types such as thermocouples and 4-20 mA loops be mixed on the same card?

A: Channel configurations are managed via Experion PKS software, allowing individual channel selection between voltage, thermocouple, RTD, and 4-20 mA current modes without altering physical hardware jumpers.

Q: Is hot-swapping supported for module replacement during online system operation?

A: The module plugs into a passive Series 8 IOTA board and supports online insertion and removal (hot-swapping) under power without disrupting C300 controller operation or field termination wiring.

Field Installation Guidelines

Press the module firmly into its designated slot on the Series 8 IOTA until the upper and lower mechanical latches engage. Connect all field wiring directly to the screw terminals on the IOTA panel rather than the module housing. Run low-level thermocouple and millivolt wiring in dedicated, shielded twisted-pair cables separated from high-voltage power distribution lines by at least 300 mm. Ground cable shields at a single ground bus point on the IOTA chassis bar to preserve 1500 VDC galvanic isolation and prevent noise injection into the internal cold junction compensation circuitry.

What's clients say about us

Excellent Emergency Support!

Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
