4-Channel SSR Solid State Relay Module - 5V

The 4-Channel SSR Solid State Relay Module - 5V, 5A is a solid state relay module with four channels and a 3.3-5VDC power supply. It is built with FR-4 double-sided printed circuit boards and uses high-quality 2A semiconductor relays. The input and output use KF128-3.81 terminal blocks for convenient wiring. The circuit includes an SS8050 1.5A high current transistor for more stable quality. The board also includes four screw fixed holes. Triggering is pulse-based, with 0-2VDC for relay ON, 3.5V for relay OFF, and 2.5V as an unknown state. The load current specification is 5-220VDC 5A, DC only.
