ACI PSG Sensor Interface Device

The PSG is a hand held programmable signal generator designed to simulate analog or pulse signals from controllers, sensors, and other building automation system components. It is designed as an aid to speed up the process of system setup and calibration. PSG is equipped with a removable cable with alligator clips for power and signal attachment. User friendly prompts on the LCD screen and a membrane switch keypad allow the user to set the output values. The analog signal can be within the range of 0 to 10 volts or 0 to 20mA. The analog output can be programmed to deliver an absolute value or a minimum/maximum toggle output. Absolute: Enter a value, and PSG will output it. MIN / MAX Toggle: Enter a minimum value and a maximum value and toggle between the two, the minimum and maximum being adjustable as it is working. The Pulse output is capable of delivering an absolute, looping, or Duty cycle type pulse. Absolute: Enter a time, and PSG outputs it. The pulse duration can be entered in seconds, minutes, or hours. Looping: Enter an ON time and an OFF time and it will continue to pulse until stopped. Duty Cycle: Signal sent as a percentage of ON time and OFF time (from 0-100%) of a selected pulse period. This signal can be an absolute percentage, or minimum/maximum toggle between the two percentages.
