6 Channel DC 5V Relay Module Relay Expansion Board with Optocoupler Insulation for Arduino

Module description:
1, The relay normally open interface maximum load: AC 250V/10A, DC 30V/10A;
2, With optocoupler isolation, strong drive capability, stable performance; trigger current 5mA;
3, Module working voltage: DC 5V, 12V, 24V three voltage versions.;
4. Each channel of the module can be triggered by a jumper to set a high level or a low level;
5, Fault-tolerant design, even if the control line is disconnected, the relay will not move;
6. With status indicator: power (green), 6-channel relay status indicator (red)
7. All module size interfaces can be directly connected through the terminal block, which is convenient and practical.
8, module size: 108mm * 50mm * 18.6mm (length * width * height)
9, with 4 fixing bolt holes, hole 3.1mm, spacing 10.5cm*4.4cm

Module interface:
1. DC+: Connect to the positive of the power supply.
2. DC-: Connect the negative of the power supply.
3. IN1-IN6: According to the setting of each channel, the corresponding relay can be controlled by high or low level.

Relay output:
1, NO1--NO6: Relay normally open interface.
2, COM1--COM6 relay common interface
3. NC1--NC6: Relay normally closed interface.

High and low trigger selection:
When COM and LOW connected, the corresponding relay is triggered by low level, and when COM and HIGH connected, it is triggered by high level.

Package Included:
1pcs REES52 6-Channel Relay Module
