Description

The WDC-24 from S&S Northern is a 24VDC DIN rail-mounted, two-zone water leak detection unit designed for integration into critical infrastructure and commercial environments. Compatible with a range of sensors including point and cable, the system supports up to 300m of sensor cable per zone (200m for cable sensors), inclusive of lead wire. WDC-24 ENC comes with a white enclosure, or the WDC-24 is available as a PCB circuit board module only.

The unit features adjustable sensitivity settings to prevent nuisance alarms and delivers a consistent excitation signal to maintain sensor performance—even in prolonged damp conditions. Each zone includes a relay output for triggering remote alarms or BMS integration with latching alarm to suit diverse application needs.
