Interface and Signal Details
The KJ3002X1-BA1 links field transmitters to the chassis backplane through a dedicated connector. Screw terminals secure loop conductors and resist vibration during continuous plant operation. Therefore, technicians achieve firm terminations without soldering or adapter kits. The card occupies one chassis slot and draws power from the shared rail.
Physical and Environmental Parameters
The card measures roughly 165 mm by 100 mm by 30 mm and weighs about 0.28 kg. Its compact housing fits crowded cabinets and keeps panel layout efficient. Meanwhile, the 0°C to 60°C operating range covers typical control room conditions. The on-board filtering suppresses noise before signals reach the conversion stage.
Why This Card Matters
Plant teams value the KJ3002X1-BA1 for its accurate loop reading and HART access. The energy storage components steady readings during electrical interference events. As a result, measurement drift drops and calibration intervals extend. Technicians also appreciate the clear channel labeling and quick slot access.
