Broyce Control Level Controller - Panel Mount, 115 [arrow/] 230 V ac 2

Dual voltage sensing relay 115/230V AC
Single or two point level control
Selectable 'Pump-up' or 'Pump-down' modes
Variable sensitivity; 2kΩ on, 5kΩ off, to 20kΩ on, 50kΩ off
LED indication of relay and supply status
Panel cutout (mm): 45 x 45
Single point level; relay energises (Pump-up) / de-energises (Pump-down) when liquid level drops below the set level electrode
Two point level; relay energises when liquid level drops below low level electrode and de-energises when level reaches high level electrode (Pump-up)
Relay de-energises when liquid level drops below low level electrode and energises when level reaches high level electrode (Pump-down)
