Athena Controls – Process Control

Located in Plymouth Meeting, Pennsylvania, USA, Athena Controls, Inc. designs and manufactures digital and analog temperature control instrumentation for applications in the process industries worldwide, ranging from plastics and packaging to food and pharmaceuticals.

Athena Controls – Process Control

Athena offers temperature control solutions in three major areas of the control loop: panel and sub-panel controllers, SCR power handlers and solid-state relays, and temperature sensors. Power Controls, and Sensors.

The Athena 4000 is a 1/4 DIN panel mounted, short metal case enclosed controller that can be used for accurate proportional temperature control of most processes.

Athena Controls - Process Control

The controller accepts thermocouple or RTD input, and offers a choice of standard single outputs for energizing most common output devices. A single, digital filtered LED display provides visual indication of various controller functions.

(delabs Notes – The reason i have put this analog controller is, that this model is a classic that may have served the industry for more than 30 Years. This is also important for academic and lab study. Still the simplest real-time control for a industrial heating system. An Usability, Serviceability and Engineering example for control engineers to understand.)
