2 Channel DC 24V Relay Module Solid State High and low Level Trigger For Arduino 240V2A

Specification: Input Power Supply: 24V DC Load Voltage: AC240V 2A Maximum operating current: 26.8mA 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
