Simple and useful transistor switched relay board allows you to control external equipment using the onboard mains rated relay from a simple 5V logic or LED signal. It can be used in automation applications, control rooms, VOX circuits etc.
The relay is triggered when a signal of over +1.4Vdc is applied to the input and turns off when the voltage falls to zero. The output is a SPDT mains rated relay with Normally Open and Normally Closed connection options capable of handling up to 250Vac or 28Vdc @ 5 Amps maximum current.
Output status indicator LED, DC power input reverse polarity protection and relay back-emf protection diode.Specifications
