<< | < | AX-WLDF - 4 Zone Waterleak detector with open/short-circuit detection
|
| |
|
|
The AX-WLDF is a range of four zone water leak detection modules designed for DIN rail mounting. This module can also detect open or short circuit sensor cables, and must be used with one of the AX-WLDF-Cx or AX-WLDF-P sensor types. The AX-WLDF can have a total of 200m of cable connected to each input. Relay outputs provide alarm signals for each individual zone. A combined alarm relay output is also available. An analogue 0-10V output provides a multiplexed signal to indicate faulty zones. The input sensitivity is adjustable to ensure false returns are not given. |
