The duplexed architecture is designed for bumpless transfer. Synchronization of the control state between the active and standby units is mandatory to ensure process stability during an automatic switchover event.\u003c\/p\u003e\n\u003cp\u003eQ: Is the unit compatible with 24 VDC power sources?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The unit supports 24 VDC input options. Verification of the specific model suffix and power module configuration is mandatory to ensure that the field-side supply matches the unit's input voltage requirements.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Secure the FCU into a standard 19-inch rack.
