Interface and Signal Details
The KJ3224X1-BK1 links thermocouple leads to the chassis backplane through a dedicated connector. Screw terminals secure the sensor wires 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 160 mm by 98 mm by 30 mm and weighs about 0.26 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 KJ3224X1-BK1 for its accurate temperature sensing and easy servicing. The energy storage components keep readings stable 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.
