24V Relay Module Optocoupler Isolation 4 Channel High Low Color: 4 Channel 24V
I like the 4 Pack because it saves a trip to the store when one relay isn't enough.
A nice touch is the generous wire clearance inside this Power Relay/Battery Isolator for crimped lugs.
A nice touch is the clear datasheet notes, which help you understand the relay behavior before you finalize your wiring.
A nice touch is the heavy duty cover, and the switch control is simple enough that you learn it quickly.
A nice touch is the Honeywell brand, which you will find helps this relay blend with other gear.
What stands out about this relay is the straightforward terminal markings, which save you time when hooking up sensors and controllers.
A nice touch is the model DEK-OE- 12DC/ 48DC/100.
You will find that the Audiopipe brand is on the relay and the paperwork.
This relay shows the Deltrol brand, and that alone makes it worth a closer look.
