Form factor dependent (typically 320–400 Ohms)
When 24V DC flows through Terminal 86 to Terminal 85, a magnetic field builds inside the coil. This magnetism pulls the switch arm down. The connection to 87a breaks, and a new link forms between 30 and 87 (NO). Power flows to the primary load. Step-by-Step Installation Guide
PLC Output (24V+) ---- Fuse (1A) ---- [A1] PLC GND (0V) ----------------------- [A2] (Flyback diode across A1-A2, cathode to A1)
Check the schematic. An AC coil will buzz and overheat on DC; a DC coil will not pull in on AC (or will chatter). f4901 11a 24v schematic install
An “11A 24V” rating does NOT mean it can switch 11A at 240V without derating. Always verify the maximum switching voltage.
Completes the power circuit for the actuator.
Ensure adequate ventilation space around the heat sinks, as operating continuously at 11A generates nominal thermal output. Step 3: Power Input & Overcurrent Protection Run a 14 AWG red wire from your 24V power source to . Form factor dependent (typically 320–400 Ohms) When 24V
: Install modules in a proper junction box (e.g., 4" x 4") to protect against dust and physical damage. Useful Documentation Resources
Double-check all physical connection points for loose strands or potential shorts. Reapply power to the primary line.

Ensure the load is powered before energizing the coil. A common mistake in f4901 11a 24v schematic install is wiring the load in series with the coil.
