Missing only one digital output for your project?
Need to pulse a device with 12 or 24V?

Convert any DDC 0-10V output into a normally open 24VAC or DC ,  (4A 24VAC  pr 2 AMP 24VDC  peak) solid state relay.

No external power supply required.
Driven by the output of the DDC controller. It uses less than 8ma from any typical analog output to turn on it's output 
Turn OFF under 2.5Vdc  ( output is Open contact)  
Turns ON above 2.5Vdc up to 12Vdc  ( output is Closed contact)    
(numbers are approximation, can vary slightly depending on wire resistance and length  Always use 0 for Off and 10V for ON. ) 
(Please use care is you are using a multiple strand cable and using 24VAC on a different pare pert of the same cable. Depending on length, the 24Vac will create an induction residual voltage on your signal wire that can create a false triggers) 

TYPICAL USAGE:  

• Modulation of small 24VAC floating actuator motors
• Driving a larger relays from a 10VDC output.
• Use an analog output to pulse a 24V or 12VDC signal
• Control of standard 24VAC thermostat signal from a 0-10VDC

 

• No external power supply is needed for the control signal, only the 0-10V from your controller.
• Can be it can be placed close to the controller or near the device to be controlled using only 2 wires.
• Small form factor , can be mounted on rails, snap track or placed into a shrink tube .

 

INPUT (control signal)
Input voltage:  2.5 to 12VDC
Turn on voltage between 2.8VDC and 3.5VDC
Current input: 8ma

OUTPUT
Max output Current:   3.5 amp under 24VAC  (peek max 4A 28VAC)
If using non PTC , input must be protected to prevent over current .

DIMENTIONS
13.5mm wide
70 mm long 
18mm wo/switch model ,  34mm high w/witch  ( depending on model with or without switch )

NOTE
If AC load is under 200ma, PTC might prevent output from working as holding current is too low.


Optional Features

• Optional PTC FUSE ( auto reset fuse 4Amp )
• Optional Switch /On /OFF/Auto

Available add on

• Snap Track
• Snap Track individually pre-cut
• Shrink Wrap 

 




Model above is with Optional ON/OFF/Auto Switch

ADA-1V2 with no options 


One channel signal converter module. For a signal change from 0..10Vdc (from external controller) into an on/off relay contact output.
