PWM
Allow 0.5 amps maximum for each device. Actuators and controller can share same transformer providing the
1
VA rating of the transformer is not exceeded and proper phasing is observed.
2
"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
3
with signal increases ) or Reverse acting function ( actuator stem moves downwards with signal increases ).
