This physical isolation prevents high-voltage inductive switching transients on load circuits from coupling into sensitive 4-20 mA HART loop protocol lines or fieldbus communication channels. The DPDT contact architecture maintains channel-to-channel isolation across both switched poles, ensuring reliable signal segregation between independent process control loops.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the CRH-2C-DC24V relay be plugged into standard DIN-rail relay sockets?\u003c\/p\u003e\n\u003cp\u003eA: Yes.
