Description
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 ,  0.9A (1000ma (1A)  peak) solid state relay.

This relay don't use any external power supply.
The integrated circuit input uses less than 8ma from any typical analog output to turn on it's output 
Between 0Vdc and 2.5Vdc  output is Open
Between 2.5Vdc up to 12Vdc  output is Closed 

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 mounted in snap track
  • Optional PTC FUSE
  • Optional Switch 



24VAC SSR HVAC RELAY
Model above is with Optional ON/OFF/Auto Switch


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