The Emerson VE4033S2B1 KJ3222X1-BA1+KJ3222X1-EA1 is a DeltaV M-Series Series 2 redundant analog input module assembly used for acquiring 4–20 mA / HART analog process signals from field instruments such as pressure, temperature, flow, and level transmitters.
It consists of:
- KJ3222X1-BA1 Analog Input Interface Card
- KJ3222X1-EA1 Redundant AI Terminal Block
Together, they provide safe field termination, signal conditioning, and redundant input capability for high-reliability process control systems.
