Aggregator Types: Analog vs. Digital


The Amper system has two different types of Aggregator: Analog and Digital. The majority of installations will use the Analog Aggregator. Unless otherwise specified, you can assume documentation is referring to the analog Aggregator.

The Analog Aggregator allows Amper to monitor real-time AC electrical current draw and determine the utilization of your machine.

When used as part of a standard installation, the Digital Aggregator monitors DC digital control signals to determine utilization by the level of activity in those signals. Both Aggregator types connect to an Amper Gateway via a CAT5 cable in order to send data online.


Note: If you are using the Digital Aggregator for automated cycle count collection, please see our article

Which Aggregator Do I need?

In most cases you will be using Amper’s Analog Aggregator. However, for certain machine types your customer success engineer or sales representative may recommend using Amper’s Digital Aggregator to achieve the highest accuracy. Your representative will review your machine list with you and let you know if any Digital Aggregators may be required.

Currently, common scenarios that may use the Digital Aggregator include:

  • Presses (such as Press Brakes)
  • Handheld Welders without access to power inputs
  • Non-CNC Centerless Grinders (particularly ones that are manually fed)

If you think you need a Digital Aggregator, or are unsure, please consult with your Amper representative to discuss in more detail.

Which Aggregator Do I Have?

Both types of Aggregator have two CAT5 ports, either of which can be used for the CAT5 cable that connects to the Gateway.

Analog Aggregator

The Analog Aggregator has 2 CAT5 ports and 8 ports for connecting the included sensor(s).


Digital Aggregator

The Digital Aggregator has 3 sensor ports, 2 digital inputs, and a power input.
