single contact welds due to an overcurrent spike?\u003c\/p\u003e\n\u003cp\u003eThe individual contact remains closed, and you must replace the module to restore normal channel operations.\u003c\/p\u003e\n\u003cp\u003eDoes the module require external 24V DC to power the internal relay coils?\u003c\/p\u003e\n\u003cp\u003eYes, the unit draws 40 mA from the 24V DC bus to energize active relay paths.\u003c\/p\u003e\n\u003cp\u003eIs an RC snubber circuit necessary when driving inductive solenoid loads?\u003c\/p\u003e\n\u003cp\u003eWe recommend installing external surge
