Exceeding this per-channel rating will cause damage to the output transistor and internal protective circuitry.\u003c\/p\u003e\n\u003cp\u003eQ: Is this module capable of sinking output current?\u003c\/p\u003e\n\u003cp\u003eA: No. The 621-6550RC is a source output module. It is designed to provide 24 VDC to the load. Ensure the field wiring configuration aligns with source-type switching requirements.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Seat the module firmly into the PLC rack slot.
