Product description
Panasonic AQG22105 Solid State Relay (SSR). PCB-mounted. Can replace mechanical relays in industrial applications where silent operation, high durability, and fast switching are desired. The relay features a high rated current, a wide AC voltage range, zero-cross switching, and LED indication.
Zero-cross switching in solid state relays means that the relay closes or opens the load when the alternating (AC) drive voltage crosses zero volts—i.e., when the voltage is at its lowest point in the sinusoidal cycle. This provides several technical advantages, especially when controlling resistive or moderately inductive loads. It significantly reduces EMI interference, increases the service life of connected loads, reduces thermal stress on the relay, and improves inrush current control.
Specifications:
- Control voltage: 4–6 VDC (compatible with 5V logic levels)
- Rated current (max): 2 A
- Load voltage: 75–264 VAC
- Phases: Single-phase
- Zero-cross switching: Yes
- Mounting: PCB solder terminals
- Frequency range: 45–65 Hz
- Weight: 4.2 g
- Temperature range: –30 °C to +80 °C
Applications:
- Industrial control systems: Especially where silent and fast AC switching is required
- Automation & machinery: For example, pump control, heating, or lighting systems
- Retrofits: An effective choice for modernizing legacy systems with mechanical relays
