Eurotherm Power Management and Control Unit, EPower
EPower is fitted with a 4 line x 10 character display with indication of the process values, and diagnostic information, along with an alarm and event message center.

Optionally, the EPower has a 32h8e remote display to allow for the process values and alarm information to be presented front of panel in a clear and unambiguous way.

Secure access to the local setpoint is also provided to allow for local control when needed.

The remote display, as an indicator, can also provide over temperature policeman functionality removing the need.
