The F3YA08-2N belongs to the Yokogawa FA-M3 and FA-M3V programmable logic controller families. This module provides an AC output interface for switching external loads such as contactors, valves, and AC lamps. Specifically, it offers eight TRIAC output points that share one common line, which simplifies wiring in panels where multiple AC loads return to the same neutral. Moreover, photocoupler isolation separates the internal logic circuit from the external AC circuit, protecting the PLC from voltage surges and electrical noise.
Furthermore, the F3YA08-2N handles a rated load voltage of 100-240V AC, covering common industrial mains supplies worldwide. Each point delivers up to 1A at ambient temperatures between 0 and 40°C. However, the per-point current derates to 0.7A when the surrounding air temperature rises to 40-55°C. Meanwhile, the total current across all eight points must not exceed 3A per common line. Therefore, engineers should calculate the combined load current carefully during system design.
The module also includes built-in surge protection through a CR absorber and varistor. Additionally, the OFF to ON response time is 1ms maximum, while the ON to OFF response time is 1/2 cycle plus 1ms maximum. As a result, the F3YA08-2N suits applications that require synchronized AC switching, such as heater control and motor starters. Besides, the unit needs no external power supply and draws only 130mA from the 5V DC backplane.
The F3YA08-2N provides eight TRIAC contact outputs with all points sharing one common terminal. First, the rated load voltage spans 100-240V AC. The maximum load current is 1A per point from 0 to 40°C and 0.7A per point from 40 to 55°C. In addition, the common line carries a maximum of 3A. The ON voltage is 1.5V AC maximum, and the off-time leakage current is 3mA maximum.
Moreover, the response time from OFF to ON is 1ms maximum, and from ON to OFF is 1/2 cycle plus 1ms maximum. The isolation method uses photocouplers, and surge protection combines a CR absorber with a varistor. Specifically, the current consumption is 130mA at 5V DC, and the module requires no external power supply. Finally, the CPU error output HOLD/RESET function is not required for this model.
The F3YA08-2N weighs approximately 150g and connects externally through a 10-point terminal block with M3.5 screws. The operating temperature range is 0 to 55°C, while storage covers -20°C to 75°C. Besides, both operating and storage humidity range from 10 to 90% RH, non-condensing. The surrounding atmosphere must be free of corrosive gases, flammable gases, or heavy dust. These ratings ensure stable operation in standard industrial cabinets.
Installing the F3YA08-2N begins with selecting a panel location that meets the temperature and humidity limits. Next, mount the module securely in the FA-M3 base unit and confirm proper backplane seating. After that, wire the AC loads and supply to the 10-point terminal block using M3.5 screws, and tighten each screw firmly. Additionally, keep AC wiring separated from signal cables to reduce induced noise. Finally, verify the total common-line current stays below 3A before applying power.
