These act as the "Common" (COM) entry points for the three separate poles in a triple-pole configuration. Normally Closed (NC) Contacts: Terminals 4, 5, and 10: Contact is maintained when the relay is de-energized Normally Open (NO) Contacts: Terminals 3, 7, and 8: Contact is made only when the 24V coil is Installation Steps
When driving a solenoid or motor, add a flyback diode (e.g., 1N5404) across the load, cathode to LOAD, anode to GND. The F4901’s internal body diode does not clamp negative inductive kick sufficiently. f4901 11a 24v schematic install
Use a Double Pole Double Throw (DPDT) switch to toggle between extend, retract, and off. This switch reverses the +/- connections to the actuator. Circuit Protection: Due to the 11A draw, use a fuse rated for at least These act as the "Common" (COM) entry points
