5V Relay Module with Optocoupler Low Level
Trigger Expansion Board for Arduino – 1, 2 & 4 channels
These relays work great,
genuine work horses, with SMD optocoupler isolation, and very stable
performance.
It
can be used as a microcontroller development board module, or as home appliance
control.
Normally open interface
and can be set to high or low triggered by jumper.
Maximum load: AC
250V/10A, DC 30V/10A.
Trigger current: 5mA
Fail safe design,
even if the control line is broken, the relay will not operate.
Convenient terminal
wiring leads, easy to connect and operate
5V relay module
TTL
control signal of 5V-12V
Controls
DC or AC signal, and controls 110V or 220V AC load.
There
is a normally open and a normally closed contact
With
power indicator
The
control pin has a pull-down circuit to prevent floating relay from
malfunctioning
