SM256 Compact Dual Pump Controller (now with bright OLED Display)
The SM256 supports Duty/Standby pumps and level sensors. This is suitable for pumping down a pit or water tank when a predefined level is met. The LCD Display shows pump activity, probe status, hourmeter and various alarm conditions. Pumps auto-alternate between cycles for even wear. Pump outlets are via two integral3-pin AC power points, suitable for common submersible pumps .

SM268 Dual Recirculating Pump Controller with LCD Display
The SM268 controller is intended for pump installations where water must circulate continuously. Suitable for Aquaculture & Hydroponics. The two pumps alternate at frequent intervals for even wear. Where flow fails, the alternate pump is activated and alarms trigger. An LCD display provides alarm status and pump usage.

SM345 Solenoid Flow Controller with LCD Display
The SM345 controller will manage a water inlet solenoid that must maintain an appropriate water level in a tank. It supports both 24VAC and 240VAC solenoid units. It features an additional input to detect tank overflow conditions and generate alarms. An internal Hourmeter and Fill Cycle counter can assist service staff in checking the ongoing integrity of a holding tank system. A separate Solenoid Jog button will force the output solenoid on for 30 seconds to further assist with integrity checks

SP96 Conductivity Probes
Suitable for most of the Alian Electronics pump range, these are a simple stainless probe that may be set to a pre-determined depth in a holding tank. Designed to fit inside standard 20mm PVC conduit, probe depth may be set by conduit length.
An air pocket around the pin prevents accidental tracking of detected water to earth.

SL96 Float Switch
Where conductivity probes are unsuitable, these reed-relay type float switches may be used to detect water levels with all pump controllers in the range.
Designed for bulkhead installation, they may be either mounted directly into the side of a tank, or into the side of square PVC duct that is is inserted into a tank.
