FIG. 9A — ML7984 WIRING WITH 10 Vdc ANALOG
CONTROL SIGNAL
For Figures 9A and 9B the following apply:
Power supply provides overload protection and disconnect means.
1
Allow up to 0.5 amps for each device. Actuators and controller can share same transformer providing the VA rating of the
2
transformer is not exceeded and proper phasing is observed. Do not mix a.c. and d.c. power sources.
3
In ML7984,"T5" and "W" terminals are connected internally. Device is compatible with 3 conductor wiring.
Use configuration DIP switches to select device functions: Direct acting function (actuator stem moves downwards with
4
signal increases to 10V/20mA) or Reverse acting function (actuator stem moves upwards with signal increases to 10V/
20mA).
Always turn power off before setting the DIP switches.
5
ML7984 will accept 0-10 Vdc control input, but will be at the end of stroke at 2 Vdc.
