Conductive Level Control

 Over view

Liquid Level Controller
Controls maximum and/or minimum levels of conductive liquids
'Pump-up' or 'Pump-down' modes selectable via switch
Adjustable sensitivity 5-100kΩ
Response times 100ms (high level); 500ms (low level)
One or two probe operation
Low voltage, ac current across probes prevents electrolysis phenomena
LED indication for supply and relay status
Ambient temperature; -20 to +60°C
DIN rail mounting, W45mm
Write-on identification tab
Dimensions (mm): H 75, W 45, D 99

Note
1. If using metal tank, connect "com" and earth to the tank
2. If supply is interrupted for ≤0.5s in "pump-up" mode, the relay will energise immediately. In "pump-down" mode relay remains de-energised
3. For single probe operation, link terminals "com" and "max"
