High insulation resistance (at least 100 Mohm at 500 V DC) and a 500 V AC withstanding voltage prevent common-mode noise coupling and ground loops across adjacent RTD channels. Thermal equalization across the M4 screw terminals minimizes parasitic thermocouple effects, ensuring accurate signal conversion when paired with system RTD input cards equipped with cold junction compensation (CJC) processing.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What screw size and torque considerations apply to the TERT*A terminal connections?\u003c\/p\u003e\n\u003cp\u003eA: The terminal block uses M4 screw terminals. Field wiring ring or spade lugs must be secured to standard M4 torque specifications to ensure low contact resistance and prevent signal degradation on RTD leads.\u003c\/p\u003e\n\u003cp\u003eQ: How does the insulation rating of the TERT*A impact noise immunity across channels?\u003c\/p\u003e\n\u003cp\u003eA: The unit features an insulation resistance of at least 100 Mohm at 500 V DC and 500 V AC dielectric strength, preventing cross-channel interference and leakage currents across all 16 contact points.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Termination:\u003c\/strong\u003e Strip RTD lead wires and crimp with compatible M4 spade or ring terminals.
