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

Convert any DDC 0-10V output to a normally open relay for up to 24VAC or 24DC ,  (4A 24VAC (4.5 Peek)   or  4 AMP 24VDC) 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)    

Note
The turn on and off numbers are approximate and can vary slightly depending on wire resistance and length.
We recommend using 0 volts for OFF and 10V for ON state. 
(Please use care is you are using a multiple strand cable that has  24VAC on a different pair in the same cable. Depending on the 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 .

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

NOTE for PTC option 
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 4 Amp )
• Optional Switch /On /OFF/Auto
