1, OMRON 5V 240V solid state relay 2A, output with resistance type fuse 240V 2A.
2, size: 55*33*25 (length * width * height) net weight: 21.5g
3, the input power supply: 5V DC (160MA)
4, the input control signal voltage:
(the state of the 0-2.5V low level relay ON)
(the state of the 3.3-5V high level relay OFF)
5, the blue KF301 terminal is connected to the line of control more convenient.
DC+: connect the power supply positive (press the relay voltage power supply)
DC-: the cathode of a power supply
CH1: 1 relay module signal trigger end (low level trigger effective)
CH2: 2 relay module signal trigger end (low level trigger effective)
High level and low level of meaning:
High level trigger refers to the signal trigger end (IN) had a positive voltage and the negative pole of the power supply, usually with the trigger end of a trigger connected with the positive pole of a power supply, when the trigger end has a positive voltage or to trigger voltage, the relay is attracted.
Low level trigger refers to the signal triggering voltage between the end and the negative electrode of the power supply is OV, or trigger terminal voltage lower voltage than the positive power supply voltage, low to can trigger, make the relay, is usually the cathode of the power supply and the triggering end of a trigger mode connection, so that the relay is attracted.
The static current voltage version of the working current of trigger voltage, trigger current
1 way 5V 0mA 12.5mA 0-2.5V 2mA
2 way 5V 0mA 22.5mA 0-2.5V 2mA
