2002 Reliable Controls™ Corporation

Outputs

MA-T™ Dual Stage Triac Outputs

The MA-T™ model has a dual stage triac. The dual stage triac 

can be connected to a two stage load.

!

Both triac stages are 

OFF

 when 

the output is commanded to 0 
volts.

!

The first stage triac (T1) is 

ON 

when the output is commanded 
to 5 volts.

!

Both triac stages (T1 & T2) are 

ON

 when the output is 

commanded to 10 volts.

Connect the two stages as 

shown in the diagram below.
