Advantages

The primary benefit of the CRM-93H lies in its exceptional versatility, as it combines multiple timing functions into a single compact unit, reducing the need for specialized hardware. Its wide input voltage range ensures seamless integration into various electrical systems without the need for voltage-specific models. The inclusion of three changeover contacts provides significant flexibility for controlling multiple circuits simultaneously, while the high-precision timing mechanism ensures consistent performance over long durations. Furthermore, its durable construction is designed to withstand the rigors of continuous operation in demanding environments.

Suitable for

• Industrial automation and process control systems
• Lighting control in residential and commercial buildings
• Heating and ventilation timing applications
• Pump and motor control sequences
• Delay-on and delay-off switching requirements

This relay may not be suitable for applications requiring extremely high-current switching beyond its 8A rating without the use of additional contactors. It is also not intended for environments with extreme moisture or corrosive gases that could compromise the integrity of the internal electronic components.

Key specifications

• Contacts: 3 changeover contacts (3P)
• Rated current: 8A
• Time range: 0.1 seconds to 10 days
• Supply voltage: 12-240V AC/DC
• Functionality: Multifunction

To use the Eti-Polam CRM-93H, mount the device onto a standard DIN rail within a suitable electrical enclosure. Connect the power supply to the designated terminals, ensuring the voltage matches the specified range. Select the desired timing function and duration using the adjustment dials located on the front panel. Once configured, connect the load circuits to the output contacts according to the wiring diagram provided on the housing. Always verify all connections before energizing the system.

What to consider before purchase

• Ensure the 8A contact rating is sufficient for your specific load requirements
• Verify that the DIN rail mounting space is available in your distribution board
• Confirm that the selected timing functions meet your automation needs
• Check that the control voltage matches your existing power infrastructure

For optimal performance and longevity, ensure the relay is installed in a well-ventilated area and protected from excessive dust or vibration. Periodically inspect the terminal connections to ensure they remain tight and free from oxidation.
