F3YD04-7N Transistor Output Module – 4-Point, 24 V DC, 2 A, Photocoupler Isolated
The F3YD04-7N is a 4-point transistor output module for industrial control systems. Each point works independently. A photocoupler isolates every channel. This design blocks electrical noise between field devices and the CPU. The module suits sequence CPUs, BASIC CPUs, and OS-free CPUs. You get fast switching, strong load capacity, and simple wiring. Use it where compact, reliable discrete output control is needed.
Key Advantages
- Independent points: All 4 outputs work separately. No shared common line.
- Photocoupler isolation: Protects the CPU from field-side surges and noise.
- 2 A per point: Drives valves, relays, contactors, and lamps directly.
- Fast response: OFF to ON in 5 ms max. ON to OFF in 3 ms max.
- Zener diode surge protector: Adds a clamp against voltage spikes.
- No external power supply: Runs from the 5 V DC bus at 85 mA.
- Compact build: 140 g module with a 10-point M3.5 screw terminal.

Installation Guide
- Wire field loads to the 10-point M3.5 screw terminal. Keep screw torque within the terminal rating.
- Use a 24 V DC load supply that matches the rated load voltage. No external module power supply is needed.
- Keep output wiring away from high-voltage cables to reduce induced noise.
- Mount in a clean panel. Ambient air must be 0 to 55 °C and free of corrosive or flammable gas.
- Confirm the CPU error output HOLD/RESET setting before you start the system.
Commissioning and Maintenance
- Check each point with a meter before you connect the load. ON voltage should stay below 0.5 V DC.
- Watch the OFF-state leakage. It should stay at or below 0.1 mA.
- Inspect terminals for tightness at routine service intervals.
- Replace the module if an output fails. Independent points allow partial operation to continue.
Compatibility Notes
The F3YD04-7N works with sequence CPUs, BASIC CPUs, and OS-free CPUs. It fits systems that use the F3YD series I/O layout. The module is a direct option for legacy machines that need a 4-point, 24 V DC, 2 A transistor output card. Oiltech Controls supports obsolete control systems with tested spare parts.
