Allow 0.5 amps maximum for each device.  Actuators and controller can share same transformer providing the 
VA rating of the transformer is not exceeded and proper phasing is observed. 
"T5" and "W" terminals are factory connected internally. Device is compatible with the 3-wire control system. 
Use configuration DIP switches to select device functions:  Direct acting function ( actuator stem moves upwards 
with signal increases ) or Reverse acting function ( actuator stem moves downwards with signal increases ). 
Use either one controller only
