Level control relay AT-DR07

voltageAC/DCelectronic

Overview
The AT-DR07 level control relay is an electronic receiver that supplies voltage to a sensor (electrode or level probe) to detect the presence of liquid and prevent water damage. When the liquid contacts the sensor, the AT-DR07 changeover contact switches to trigger an alarm, a signal or a control command. Designed and manufactured in France.

Functions

• Fixed level detection (ON-OFF probe)
• Level regulation (difference between two probes)

Operating principle
The relay is fitted with two electrodes. When the liquid contacts these electrodes, the electrical circuit closes. Depending on the connected device, the output provides an alarm or a NO/NC control contact.

Recommended accessories

• AT-AQUALARM (conductive level sensor)
• AT-SONDE (electrode for detection of conductive liquids)
