Emerson KJ3225X1-BA1 DeltaV RTD/Resistance Input Card

The KJ3225X1-BA1 captures precise temperature and resistance measurements for DeltaV process control loops. This input card serves RTD sensors and resistive devices through eight dedicated channels. Engineers select this module for its stable readings and simple chassis installation in demanding plant environments.

Input Channels and Signal Ratings

The KJ3225X1-BA1 provides eight input channels that accept RTD and resistance signals. Each channel supports two-wire, three-wire, and four-wire RTD wiring configurations. Furthermore, the card measures resistance across a broad range for flexible sensor matching. It operates across a temperature range of 0°C to 60°C.

Physical Dimensions and Component Count

This input card measures approximately 130 mm in length, 80 mm in width, and 25 mm in depth. The unit weighs about 0.20 kg, so technicians seat it quickly into the controller chassis. The assembly includes eight input channels, one backplane connector, and two mounting rails. In addition, front-panel indicators show channel status and fault conditions clearly.

Energy Storage Characteristics

The KJ3225X1-BA1 contains no internal energy storage components because it draws power directly from the chassis backplane. Therefore, the card requires no battery replacement and generates minimal heat. This architecture also keeps long-term maintenance costs low.

Integration Notes

System integrators pair the KJ3225X1-BA1 with DeltaV controllers that monitor temperature-critical process points. The eight-channel layout reduces card count per cabinet and simplifies loop documentation. Consequently, engineers commission measurement points faster during plant upgrades.
