PRODUCT INTRODUCTION
2 Channel 5V DC Relay Module Solid State High Level SSR AVR DSP
0-2.5V low state relays ON)
(3.3-5V state high relay OFF)
5, blue KF301 terminals to the control line is more convenient.
Module Interface:
Input section:
DC +: positive power supply (according to the relay voltage supply)
DC-: negative one
CH1: 1 relay module signal triggering end (low to trigger active)
CH2: 2 relay module signal triggering end (low to trigger active)
High and low meanings:
High trigger finger is a signal to the trigger terminal (IN) between the negative power supply and has a forward voltage, usually with a trigger and trigger the positive terminal connected to the power supply, when the trigger end has triggered positive voltage or reach When the voltage, the relay is energized.
Low voltage trigger refers to OV, or trigger voltage lower than the voltage supply terminal positive signal to trigger the end of the negative power between low enough to trigger the voltage, so that relay, usually the A negative trigger and the trigger end of the power connection, the relay is energized.
Electrical parameters:
Voltage version quiescent current working current trigger voltage trigger current
1 channel 5V 0mA 12.5mA 0-2.5V 2mA
2-way 5V 0mA 22.5mA 0-2.5V 2mA
Product description:
1. The module power supply: Power must be DC voltage to match the voltage relay
