Relpol M93R Signaling Module with Red LED and Varistor, 110-230V AC/DC

The Relpol M93R signaling module is a specialized component engineered for industrial control systems, providing both visual status monitoring and electrical protection. This compact device is equipped with a high-visibility red LED indicator that allows operators to quickly identify the operational state of a circuit. Furthermore, it incorporates an integrated varistor designed to suppress voltage surges, thereby safeguarding sensitive relay components and extending the lifespan of the control system.

Advantages

The primary benefit of the Relpol M93R module is its dual-functionality, which combines clear visual signaling with robust surge protection in a single, space-saving unit. Its wide operating voltage range of 110-230V AC/DC makes it highly versatile for various electrical environments, reducing the need for multiple specialized components. The grey housing is designed for seamless integration into standard automation panels, ensuring a professional and organized installation while maintaining high reliability in demanding industrial conditions.

Suitable for

• Industrial automation control panels
• Relay status monitoring systems
• Electrical circuit protection against voltage spikes
• Control cabinets requiring clear visual feedback

When it may not be suitable

This module is not intended for use in low-voltage DC circuits below 110V, as it will not function correctly. Additionally, it is not suitable for outdoor environments without appropriate protective enclosures, as it is not rated for direct exposure to moisture or extreme environmental contaminants.

Key specifications

• Operating voltage: 110-230V AC/DC
• Indicator type: Red LED
• Protection feature: Integrated varistor
• Color: Grey
• Application: Industrial relay and control systems

How to use

The Relpol M93R module is designed for easy installation directly onto compatible relay sockets. Ensure that the power supply is disconnected before mounting the module to the relay. Once securely attached, the module will automatically engage the LED indicator and the surge protection circuit when the relay is energized. No additional configuration is required, as the device is pre-wired for immediate operation within the specified voltage range.

What to consider before purchase

• Verify that your control system voltage falls within the 110-230V AC/DC range.
• Ensure compatibility with your specific relay socket type.
• Confirm that the physical space in your control panel allows for the addition of the module.

Usage recommendations

For optimal performance and safety, always ensure that the module is firmly seated in the relay socket and that all electrical connections are tightened according to standard industrial practices. Regularly inspect the LED indicator to ensure system status is being reported accurately.
