Product: Solid State Relay G3MB202P (G3MB202P5VDC variant) Key benefits Reliable, maintenance-free switching: solid-state construction means no mechanical contacts to wear out, providing long service life for frequent switching. Compatible with common 5V control logic: designed to operate from a 5VDC input, making it easy to interface with microcontrollers, PLCs, and other 5V control circuits. Safe AC switching for small loads: rated to switch up to 240VAC at 2A, suitable for many low-power AC applications where a compact, silent relay is required. PCB-ready package: intended for PCB mounting, simplifying integration into custom electronics and control boards. Important attributes Function: DC input to AC output solid state relay (DC-AC type) for switching AC loads. Input: 5VDC control voltage (G3MB202P5VDC indicates the 5V input version). Output: 240VAC switching capability, maximum current 2A. Form factor: PCB SSR designed for direct mounting on printed circuit boards. Operation: Solid-state switching (no moving parts), suitable for silent operation and high switching cycles. Technical specifications (concise) Model: G3MB202P (5V input variant: G3MB202P5VDC) Input voltage: 5VDC control Output rating: 240VAC, 2A Practical use scenarios Home automation: Interface an Arduino or Raspberry Pi (5V logic) to switch AC lighting or small fans on a custom PCB without mechanical relay noise. Appliance control and prototyping: Control small heating elements, indicator lamps, or control circuits in lab prototypes where compact PCB mounting and frequent switching are required. Industrial control panels: Use on control boards to drive low-current AC loads while keeping the control circuitry isolated on the PCB and avoiding mechanical relay maintenance. Installation and compatibility notes Designed for PCB mounting; ensure correct orientation and secure soldering to handle rated current. Match load type and inrush characteristics to the 2A, 240VAC rating; avoid applications with high startup inrush currents that exceed the relay’s rating. Use appropriate heat dissipation and protection (fuses, snubbers if required by load) according to application needs. Models and identification G3MB202P is the base model. The suffix G3MB202P5VDC specifies the 5VDC input version as used for 5V control systems. This SSR provides a compact, 5V-compatible solution for switching AC loads up to 240VAC/2A on a PCB, offering silent operation and extended life compared with mechanical relays.
