Built‑in function
33CAJD temperature transmitter module receives resistance signal from field RTD temperature sensors,converts measured temperature value into standard 4‑20mA current signal for Spec‑200 control rack processing. On‑board zero‑span potentiometers support on‑site calibration without removing module from rack. Shielded housing suppresses industrial electromagnetic interference for stable temperature acquisition in petrochemical and power plant process loops.
Product Brief
33CAJD belongs to Foxboro Spec‑200 legacy DCS spare‑part family,obsolete original automation component. It must be installed inside matching Spec‑200 instrument rack,requires correct field RTD sensor wiring. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation
