RIA46 process indicator with control unit

Field of Application

The RIA46 field indicator displays, evaluates, and calculates analog measured values. It features an integrated loop power supply (LPS) for powering two-wire sensors. Its universal inputs allow for the connection of current, voltage, RTDs, and TCs. Limit values can be monitored, and relays can be switched accordingly. Process signals can be forwarded through analog outputs. The integrated "differential pressure" application package enables quick and easy commissioning for differential pressure applications.

The RIA46 field meter includes:

• A display
• Analog inputs for process and status signals
• Analog and digital outputs
• An interface for configuration

All measured and calculated values can be used as signal sources for display, outputs, relays, and interfaces.

Applications

• Process recording and supervision
• Process control
• Signal adjustment and conversion

Benefits

• Clear display 5-digit, 7-segment LC display with backlight
• Flexible input options One or two universal inputs
• Switching functions – Optional two relays
• Data storage Min/Max value storage for process analysis
• Advanced calculations – One or two calculated values with a linearization table
• Digital status output – Open Collector output for process control
• Safety compliance – Optional SIL 2 approval for enhanced safety
