VE4003S5B1

Eight-channel thermocouple and millivolt input assembly for DeltaV M-series I/O. The VE4003S5B1 termination block adds local cold-junction compensation for supported thermocouple types.

The card has channel-to-system isolation, but inputs within each four-channel group are not mutually isolated. Ground potentials in one group must remain within the stated ±0.7 V DC common-mode relationship.

External CJC is useful when the actual cold junction is remote from the terminal block. One input can be configured to measure that junction for the remaining thermocouple inputs.

No. Cold-junction compensation applies to characterized thermocouple inputs and is not applied when a channel is configured for mV measurement.

Its open-sensor circuit uses less than 70 nA and has a stated detection time of 10 seconds, so control and alarm logic should account for that interval.

Both serve thermocouple/mV input duties, but S5B1 is the CJC termination. A change to S4B1 requires the junction-compensation method and configured thermocouple scheme to be reassessed.
