This partitioning prevents common-mode noise and electrical faults from propagating across the entire output bank.\u003c\/p\u003e\n\u003cp\u003eQ: Can this module be used for both AC and DC load switching?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the relay contacts are rated to handle both DC (24–125 V) and AC (100–240 V) voltages. Always ensure that the total switched load current and voltage remain within the manufacturer's specified safety envelopes to avoid contact welding or excessive arcing.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Install the module in an environment where temperatures remain between -10°C and +55°C.
