Features:
1 This module conforms to the safety standard, the control area and the load area have isolation slot;
2 With power and relay instructions, pull in light, disconnect not bright;
3 When the signal input signal, the common end and the beginning will be open;
4 Can be used as MCU development board module, can be used as home appliances control;
5 Control DC or AC signal, can control 220V AC load;
6 There is a normally open and a normally closed contact;
7 Blue KF301 terminal connecting control line is more convenient.

Electrical parameters:
Voltage version quiescent current operating current trigger voltage trigger current
5V 4mA 65mA 0-2V 2mA

Note:
1. High level flip-flops shows that there are trigger mode of the voltage between the signal input terminal and the ground; That is to say it is a way of short circuit trigger between signal input and VCC positive pole.
2. Low level flip-flops shows that there are voltage for OV trigger mode between the signal input terminal and the ground. In a word, it is a way of short circuit trigger between signal input and GND negative pole.

Package Included:
5pcs 1 Channel 5V Relay Module Shield
