10A TTL Relay Boards

Back to Products  Home

 

 

These are nice compact boards for controlling devices that require higher loads (lights, heaters, solenoids, etc.) with TTL-level signals.  These boards can switch AC or DC loads up to 10A (although, I wouldn’t use it for anything that drew that much).  These boards are a little larger than the 1A version and have relays that have normally open and normally closed contacts.  They require 12VDC for operation and 1 TTL signal per relay circuit.  If you are switching higher current solenoids or relays, I make suppression boards that provide fusing and back EMF suppression.  Contact me for pricing/more information.  The Relay Boards are available in the following versions:
