Description
4 Channel DC 12V Relay Module Solid State High and low Level Trigger For Arduino – ROBOZONE
Input Power Supply: 12V DC
Load Voltage: AC240V 2A
Maximum operating current: 48.8mA
Trigger mode: high level / low level
Input control signal voltage:
(0-2.5V low state relay OFF)
(3.3-5V state high relay ON)
Blue KF301 terminal connection control line is more convenient.
Module interface:
DC +: positive power supply (by relay voltage power supply)
DC-: connect power negative
CH: Relay Module signal triggering end (Low level trigger effective)
Note: Power must be DC voltage and need to be consistent with the voltage relay
Package Included:
1x High Level / Low Level Relay
