The process transmitter identifies, evaluates and calculates analog measured values. It can supply power to two-wire sensors via the built-in loop power supply. Universal inputs allow the connection of current, voltage, resistance thermometers and thermocouples. Limit values can be monitored and relays switched. Process signals can be transmitted via the analog output. The built-in “differential pressure” application package allows fast and easy commissioning of differential pressure applications.

Advantages

SIL 2 approval (optional), marine approval

1 or 2 calculated values and linearization table

Stores minimum/maximum values

5-digit 7-segment backlit LCD display

1 or 2 universal inputs

2 relays (optional)

Digital status output (open collector)

Areas of application

The RMA42 process transmitter has analog inputs for display, process and status signals, analog and digital outputs, and a setup interface. Connected sensors can be supplied by the built-in LPS. All measured and calculated values can be used as signal sources for display, outputs, relays and interfaces.
