Description

Analog measured values are indicated, evaluated and calculated by the process meter. With the integrated loop power supply two-wire sensors can be powered. The universal inputs enable the connection of current, voltage, RTDs and TCs. Limit values can be monitored and relays can be switched. Via analog outputs process signals can be forwarded. The integrated application package "differential pressure" allows the quick and easy commissioning for differential pressure applications.

Field of application

The RIA45 panel meter exhibits a display, analog inputs for process and status signals, analog and digital outputs, and an interface for configuration. Connected sensors can be powered by the integrated LPS. All measured and calculated values are available as a signal source for display, outputs, relays and the interface.
