ALLNET ALL4456 Water Leakage Sensor Module (Electronics Only, Probes Not Included) ALL4456_o._Schwimmer

Detects water presence with a response time under 1 second via a potential-free change-over relay contact rated up to 24V DC / 1A or 230V AC / 0.5A. This ALLNET ALL4456 module is the electronic core for water leakage monitoring in ALLNET MSR systems, requiring external conductive probes (not included) to complete the sensor.

Overview

The ALLNET ALL4456 is a water leakage sensor electronics module designed for integration into ALLNET MSR monitoring systems. It operates on a 10–15V DC supply and consumes a maximum of 50 mA. The module features one input for a pair of external conductive probes, which are not included. When water bridges the probes, the module triggers an alarm, indicated by a red LED and an internal buzzer (switchable). A green LED indicates power status. The relay output provides a change-over contact, selectable between normally open (NO) and normally closed (NC), allowing flexible integration with alarm panels, PLCs, or other control equipment.

What stands out

• Fast detection: response time under 1 second.
• Flexible relay output: change-over contact, NO/NC selectable.
• Audible and visual alarm: internal buzzer and red LED.
• Wide operating temperature range: 0°C to +50°C.
• Supports long sensor cable runs up to 100 meters (depending on cable quality).
