DZ5 flood sensors on a DIN rail are designed to detect water leaks in environments such as heat exchanger stations or boiler rooms. These conductivity-type sensors are connected to probes, such as the DS type, using a two-wire cable with a recommended maximum length of 5 meters. The device has two relay outputs that react to the connection of the probe electrodes with the conductive medium, thereby signaling flooding. In case of flooding, the red LED lights up on the device. The sensor is designed for direct mounting on a DIN rail and is powered by 24 VDC or 24 VAC.

Specifications

• Two relay outputs with different switching modes depending on the flooding condition.
• Supply voltage 24VDC/24VAC with a maximum input of 6VA.
• Flood signaling using a red LED.
• A time delay of approx. 1s between the activation of the probe and the activation of the outputs to avoid false alarms.
• DIN rail mounting for easy installation.
• Galvanic separation of relay outputs from other parts of the device.
• Operating and storage temperature -20 to 60°C, protection IP20.

Note: The device is not intended for permanent level sensing or for regulating the level, but for signaling malfunctions of space flooding.
