12Vdc powered TTL compatible switched dual mains rated relay board that allows you to control external equipment using 5V logic, DC Low or DC High trigger signals.
Ideal for use with boards like our 3133, 3148 and 3154 that have an active low open collector output.
Each relay has an independent trigger input for either LO (0 - 0.8V) or HI (2.4 - 12V) signals. 2 LED relay status indicators.
The circuit is based around a ULN2003A Darlington array IC. Please refer to the User Manual below for full operating details.
Also available in 24V powered version (Order Code AS3156-24V).
