Multifunctional w-automat type timer relay from 0.1 seconds to 100 hours (12-240 V AC/DC)

ERV-08M Multifunction Timer Relay

The ERV-08M is a multifunction timer relay designed for applications requiring time-based control, in industrial, commercial, and residential settings. Its versatility and ease of use make it an effective solution for electrical process automation.
This device allows for precise adjustment of the actuation time using a dual regulation system: range selection (time scale) and fine adjustment, facilitating accurate settings even over long intervals. As shown on page 1 of the document , the user can select different time scales and adjust the desired value easily and intuitively.
The ERV-08M has multiple timing ranges, from seconds to hours:

• 10 s / 100 s
• 10 min / 100 min
• 10 h / 100 h

During operation, the device starts timing upon receiving power, indicated by a flashing LED. Once the set time has elapsed, the relay switches from a normally closed (NC) contact to a normally open (NO) contact, maintaining this state until power is interrupted.

Main features:

• Multifunction timer relay
• Wide timing range (seconds to hours)
• Precise adjustment via dual selector (scale + fine adjustment)
• Relay output with changeover contact (NO/NC)
• LED status indicators (power and output)
• High reliability and easy setup

In terms of technical specifications, the ERV-08M stands out for its great compatibility:

• Power supply: 150 – 260V AC / 12 – 240V AC/DC
• Frequency: 50/60 Hz
• Power consumption: <4VA
• Contact capacity: 5A / 250V AC
• Operating temperature: -20°C to +55°C

Its compact design allows for DIN rail mounting, facilitating its integration into electrical panels. Furthermore, its terminal connection ensures quick and secure installation.
Maintenance is minimal, requiring only occasional cleaning without harsh chemicals. For safe use, it is recommended to avoid humid environments and incorporate safety devices such as switches or circuit breakers.
The ERV-08M is a practical, robust and precise solution for timed control in a wide variety of electrical applications.
