Process transmitter with control unit
Universal transmitter, loop power supply, barrier and limit switch in one device!
Analog measured values are indicated, evaluated and calculated by the process transmitter. 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 RMA42 process transmitter 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.
