RM-8X24V - Octal Relay Module 24V for Arduino PIC ARM DSP AVR

This board is an 8-channel relay control.
Each relay is switched by an optocoupler with an added driver.

You can select the switching level HIGH (24VDC) or LOW (0VDC) by jumpers for each channel.
Not for microcontrollers!For that you should use this.
Each channel has an indicator LED.
Current consumtion 20mA / channel

Relay output is SPDT for each channel with max. 10 AMPs @ 125/250VAC or 28/30VDC.
Type of relay is SRD-24VDC-SL-C.
You need a power supply with 24VDC!
A green led shows the presence of the power.
