inputs?\u003c\/p\u003e\n\u003cp\u003eA: The module uses an internal 16-bit A\/D converter running at a sampling speed of 100 samples per second to convert voltage, 4-20 mA current, and RTD inputs.\u003c\/p\u003e\n\u003cp\u003eQ: Can Pt100, Ni120, and Cu50 RTD sensors be configured simultaneously on the same unit?\u003c\/p\u003e\n\u003cp\u003eA: Yes, channels are independently configurable via software parameters to accept specific RTD curves alongside standard voltage and current signals.\u003c\/p\u003e\n\u003cp\u003eQ: Is online hot-swapping supported for the AMN33 S2 module during system operation?\u003c\/p\u003e\n\u003cp\u003eA: Hot-swapping is permitted provided the retaining latches are fully disengaged and proper ESD grounding procedures are followed during

rack frame, pushing firmly until the locking mechanisms click into place.\u003c\/li\u003e\n\u003cli\u003eSecure top and bottom retaining screws to ensure proper chassis grounding contact and vibration resistance.\u003c\/li\u003e\n\u003cli\u003eRoute field input signal lines (voltage, 4-20 mA, RTD) in separate grounded wire channels, keeping them at least 300 mm away from high-voltage AC cables.\u003c\/li\u003e\n\u003cli\u003eConnect all cable shield drain wires to a single point on the cabinet system ground busbar to eliminate ground potential
