Endress+Hauser RMA42 LCD Multi-Function Panel Meters for Voltage, Resistance, Temperature, Current

This multi-function panel meter is a process indicator designed for industrial measurement and monitoring tasks. It displays electrical and thermal parameters on an LCD and operates across typical process environments. The instrument is intended for panel mounting and provides a clear numerical readout for integration into control systems where accurate monitoring of current, voltage, resistance and temperature is required.

• 5-digit display delivers finer resolution for process readings
• Measures 4mA to 20mA and 0mA to 20mA for loop and direct signals
• Accepts 10V to 30V inputs for flexible voltage monitoring
• Detects resistance from 30Ω to 3000Ω for sensor diagnostics
• Operates between -20°C and 60°C for varied ambient conditions
• CE marked for adherence to relevant regulatory standards

• Suited to control panels monitoring 4-20mA transducers
• Ideal for verifying thermistor circuits using resistance ranges
• Used with PLC inputs requiring five-digit precision
• Can be used for on-site voltage checks up to 30V
• Appropriate for temperature indication within standard process ranges

It accepts current loops down to 4mA and up to 20mA and supports direct voltage inputs within a 10V to 30V range.

It can measure resistance values starting at 30Ω and up to 3000Ω, allowing use with a broad set of resistive sensors.

The device is rated to operate at temperatures from -20°C to 60°C, covering many industrial ambient conditions.

The instrument provides a five-digit LCD readout, supporting fine numerical resolution for process measurements.

The instrument requires a panel installation depth of 118mm, suitable for standard DIN-style mounting arrangements.
