This requires careful circuit design, especially when driving multiple solenoids or lamps simultaneously from the same group's power feed.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCan I use this module to directly control a small 12V DC relay?\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eYes, but ensure the relay coil current is below 0.5A. You will need a separate 12V DC power supply for the relay coil, as the module only switches the path to its own 24V L+ supply terminal.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHow does the \"safety-related tripping\" function work without being a safety module?\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eA separate safety controller (like an F-CPU) can send a stop command over PROFIsafe. This command tells the standard CPU to set all outputs of this module to 0 in a failsafe manner, achieving the required safety level for the connected machine.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWhen would I use the parallel switching of two outputs?\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eUse this for redundancy on a critical load (like a cooling fan) by connecting it to two outputs. You can program them to switch together, so if one output fails, the other maintains operation, increasing system availability.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eThe datasheet mentions a 0.5 Hz limit for inductive loads. What happens if I switch faster?\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eExceeding this frequency with inductive loads (like solenoid valves) causes excessive heat in the module's internal protection circuitry. This can lead to premature failure or nuisance tripping of the electronic short-circuit protection.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e© 2025 Ubest Automation Limited.
