Description

The RME2-AI is an analog input module designed for industrial and automation applications. It allows users to monitor and control analog signals from various sensors and devices. The module is particularly suited for applications requiring the measurement of current loops (4-20 mA) and voltage ranges (0-10V).

Key Features and Functions

Analog Inputs:

• The RME2-AI is equipped with 8 analog input channels.
• Each input can be configured to handle either 0-10V voltage signals or 4-20mA current loop signals.
• The input resolution is 12 bits, providing accurate measurements.
• For current inputs, the module has an input impedance of 62 ohms.

Signal Conditioning and Processing:

• The module can calculate an average reading from the input signals, with options to specify the number of samples used for averaging.
• It also supports scaling, allowing conversion of raw input values into engineering units (e.g., converting a 4-20mA signal from a temperature transducer to a temperature range in degrees Celsius).

Communication Capabilities:

Ethernet:

The RME2-AI includes an Ethernet port (10/100 Mbps) for network connectivity. This enables communication using various protocol.

• • Modbus TCP: For industrial automation.
  • HTTP: For web-based monitoring and configuration.
  • DHCP, ICMP, ARP: For network management.
  • SNMP: For network monitoring.
  • MQTT: For IoT applications.

Serial Port:

It also has an RS-232 serial port, which can be used for Modbus RTU/ASCII communication in gateway mode.

Configuration and Management:

• The module is configured through a web-based interface, making it accessible from any device with a web browser.
• It can obtain an IP address automatically via DHCP or be assigned a static IP address.
• The configuration interface is password-protected to ensure security.
• Firmware updates can be performed through the web interface.

Monitoring:

• The RME2-AI provides monitoring capabilities through its web interface.
• It offers two monitoring modes:
  • Administrator’s Monitor: Provides detailed information, including analog values, scaling data, A/D converter values, and alarm statuses.
  • User’s Monitor: Displays user-selected variables, alarm statuses, and scaled values.

Alarm Functionality:

• The module supports configurable alarm thresholds (high and low) for each input.
• Alarms can trigger SNMP traps for notification.

Data Output and Integration:

• The RME2-AI can provide data in various formats:
  • Modbus TCP registers: For integration with industrial control systems.
  • CSV and XML files: For data logging and analysis.
• It supports MQTT for integration with IoT platforms, allowing for the publishing of measured values and subscription to topics for configuration and data exchange.

Physical Specifications:

Overall, the RME2-AI is a versatile device that can be adapted to a wide range of industrial monitoring and control applications due to its flexible input options, communication capabilities, and configuration features.
