  • Page 1 THE APOLLO INTELLIGENT METER SERIES MODEL IMP INSTRUCTION MANUAL...
  • Page 2 INTRODUCTION The Intelligent Meter for Process Inputs (IMP) is another unit in our multi-purpose series of industrial control products that is field-programmable to solve multiple applications. This series of products is built around the concept that the end user has the capability to program different personalities and functions into the unit in order to adapt to different indication and control requirements.

    If provided by the equipment may be impaired. Do not use the IMP to directly command motors valves, or other actuators not equipped with safeguards. To do so, can be potentially harmful to persons or equipment in the event of a fault to the unit.

  • Page 6: General Description

    THEORY OF OPERATION filtering enhances the stability of the reading. Programmable remote input The IMP employs a microprocessor to perform the A/D conversion on the “E1-CON” pin can be utilized to control a variety of functions, such as totalizing, input signal via a voltage-to-frequency converter. It digitally scales the result, alarm control, display hold or tare operations.
