Product Brief:

12P1731X082, alias KJ3002X1‑BG2 and VE4003S5B1, is legacy 8‑channel thermocouple mV input module for Emerson DeltaV DCS system. It receives millivolt‑level signals from field thermocouple temperature sensors. Built‑in CJC cold‑junction compensation ensures accurate temperature measurement. After isolation filtering and A/D conversion, temperature process data is transmitted to DeltaV main controller through rack backplane bus. It supports thermocouple wire break/open‑circuit detection. On‑board LED gives visual feedback of power, channel running and fault conditions. This is EOL discontinued spare part,widely used for maintenance and renovation of petrochemical and thermal power plant DeltaV DCS equipment. Please confirm hardware revision and rack compatibility before purchase. Strict ESD anti‑static protection shall be followed during installation and replacement。
