Description

The RME1-AI analogue input module is 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 (4-20mA) and voltage ranges (0-10V).

Key Features and Functions

Analog Inputs:

• The RME1-AI is equipped with 8 analogue 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 150 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 RME1-AI includes an Ethernet 10BaseT, RJ45 connector 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.

Serial Port:

Pluggable terminal blocks for device configuration

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 RME1-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 RME1-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.

Physical Specifications:

Overall, the RME1-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.

The RME1 series has been updated with the RME2 series, which allows MQTT integration, lower power consumption and impedance on analogue inputs. Limited stock remains from the RME1 series.
