Industrial 24V 120mm fan

The OEM Industries MMF-12C24RH-FC1 is a 120mm square fan built for 24 V DC systems. It draws 0.27 A through a four-pin connector and uses a dual ball bearing. The unit is designed for PLC and inverter cabinets such as ABB or Yaskawa devices where a standard PC header is not present.

Dual ball bearing and four-wire control

The 2 ball bearing construction resists dust and vibration better than sleeve alternatives in continuous industrial duty. A 38 mm thick frame fits standard 120 mm cut-outs while the four-wire lead provides both power and speed feedback to the host controller. No LED lighting is fitted, keeping the face plain for clean-room or enclosed cabinet use.

Replaces worn Melco 55FA80521 units

This fan directly substitutes the original Melco 55FA80521 when airflow drops or bearing noise appears in ABB and Yaskawa drives. The jump is worth it when the existing 24 V supply is confirmed and the four-pin keying matches the board header. It is not for builders needing 12 V PC PWM control or standard motherboard fan headers.

Questions about this item

What does the 4-pin connector on the MMF-12C24RH-FC1 control?

The 4-pin connector supplies 24 V power and carries a PWM signal so the inverter can regulate the fan speed precisely.

What clearance does the 38 mm frame depth of this 120 mm fan require?

The frame is 38 mm deep, so the mounting location must provide at least that much space behind the 120 mm screw pattern.

How is the MMF-12C24RH-FC1 wired into a PLC cabinet?

Connect the four wires to the matching 4-pin header on the ABB or Yaskawa inverter; the keyed plug prevents reversed polarity, which is the most common wiring error.
