9.3  Vernier Output - Master/Slave Configuration 

In  a  Master-

Slave  Configuration,  the  master  unit’s  Vernier  output  should  be 

used for driving the SSR or SCR Power Control. 
 

10.  Electrical Specifications 

Power Input 

24VAC -15/+15% 50/60Hz < 10VA. 

24V Thermostat Power 

-  

Aux Output Rated at

 

24VAC @ 500mA max. 

Brown Out Protection 

Stages restart from zero upon loss of power.

 

Command Inputs 

0-5V,  1-5V,  0-10V,  2-10V,  0-20mA,  4-20mA,  0-135Ohm.  
Selectable via dipswitch. 

Stages 

Selectable  from  1  to  16  stages  via  dipswitch.    More  than  8 
stages requires an additional NWVS setup for slave operation.

 

Stage Outputs 

30  VAC  @  1.0A  SPST  Mechanical  Relays  w/MOV  protection, 
up to a max of 5A total for all of the stages.   Up to 8 stages per 
board.  Use a Class 1 ( properly fused ) or Class 2, CSA or UL 
recognized transformer for power supply & relay outputs. 

Vernier Output 

Selectable via dipswitch # S1-6:   

 

 

Time  Proportioning  (S1-6  OFF): 

Current  limited  ~24VDC 

nominal.  Time Proportioned 4 second cycle time for driving an 
SSR. 

 

 

Analog  (S1-6  ON): 

0-10VDC  output  for  driving  an  SCR  power 

control.    10VDC  output  tolerance  is  +5/-8%  at  24VAC  power.  
10VDC output tolerance is +5/-25% at 20VAC power.           

Slave Output 

0-5V

 

output for expanding beyond 8 stages.

  

Stage Output Modes 

-

  LIFO or FIFO Selectable via dipswitch.
