=====Relais Board =====
Double, tripple or quad relais module from dx.com, Alibaba or Amazon
==a==Using 5 V control voltage from Arduino ==a==
For 5 V systems like [[Arduino]] connect Vcc to 5 V and set the JD-VCC jumper.
The inputs are low-active. The microcontroll must deliver a low level to activate the relais.

==a==Using 3.3 V control voltage from Raspberry Pi==a==
For 3.3 V systems like Raspberry Pi remove the JD-VCC jumper. Conect 5 V to the JD-VCC side of the jumper.
Connect 3.3 V to VCC.

SRD-05VDC-SL-C says
- SRD: relais model
- 05VDC: Voltage the relais coil should be 5 V (this is JD-VCC)
- S:Sealed type
- L: coil power consumption is 0.36 W
- C: Contact form type C
10A 250VAC 10A 125 VAC says: The voltage at the relais contacts should not exceed 250 V and 10 A for alternating current
10A 30VDC 10A 28 VDC says: The voltage at the relais contacts should not exceed 30 V and 10 A for direct current
==a==Power consumption==a==
71.4 mA was found in the [[https://www.ghielectronics.com/downloads/man/20084141716341001RelayX1.pdf data sheet]].
I was measuring 80 mA per channel when active (relais on).
