SFK-112DM Relay 12VDC 20A 250VAC 4Pins Air Conditioner Water Heater Relay

Description Additional information Reviews (0) Description This 5V 1 Channel SSR G3MB-202P Solid State Relay Module 240V 2A Output with Resistive Fuse is based on the Omron G3MB SSR relay which can control up to 2A at 240VAC. .This is a 1 Channel SSR Solid State Relay module which has 3 separate terminals, NO (Normal Open), COM (Common), NC (Normal Closed) A Solid State Relay is similar to a mechanic relay where it can be controlled through a digital signal. Solid State Relay generates no noise and has a much longer lifespan in compared to the traditional mechanic relay. When the input logic voltage is applly to the coil, the NC will disconnect from the COM breaking the conductivity between the two. At the same time, the NO will connect with the COM allowing conductivity between them. Depending on your wiring this will turn on or off the connected load. Input parts : DC+: connect power positive DC-: connect power negative CH1: relay module signal trigger point (Effective low-level trigger) Features : Has been assembl, and the electrical test pass. It can be control directly by Microcontroller Input control signal voltage: 0-2.5V status low level, relay OFF 3-5V status high level, relay ON
