DC 5V 1 2 4 Channel 1-CH 2-CH 4-CH Relay Module High Level Solid State Relay Trigger Effective SSR AVR DSP Board for Arduino

2, size: 57*55*25 (length * width * height) net weight: 40g
3, the input power supply: 5V DC (160MA)
4, the input control signal voltage:
(0-2.5V the state of low level relay OFF)
(3.3-5V high level relay ON)

Module interface:
Input part:
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 (high level trigger effective)
CH2: 2 relay module signal trigger end (high level trigger effective)
CH3: 3 relay module signal trigger end (high 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 is usually between, and the triggering end of a trigger connected with the positive pole of a power supply, when the trigger end has a positive voltage or reached the trigger voltage, the relay is attracted.

The static current voltage version of the working current of trigger voltage, trigger current
1 way 5V 0mA 13.8mA 3.3-5V 2mA
2 way 5V 0mA 26.8mA 3.3-5V 2mA
3 way 5V 0mA 37mA 3.3-5V 2mA
4 way 5V 0mA 48mA 3.3-5V 2mA

Usage:
Module power supply: the power supply must be consistent with the DC voltage, the voltage relay
