Can this assembly connect directly to any PLC analog input?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNot necessarily. The input must accept the +1 to +6 VDC signal range and provide compatible signal conditioning. Check input impedance, isolation, grounding, resolution, and scaling before connecting the transducer. A 4–20 mA-only input requires an appropriate signal conversion solution.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3.
