Make your selection to suit your requirements.

Inputs can be from cabled float switches such as B8 (see accessories), or from

Rigid probes such as G1X  series, or from

R4/5 series relays in a T4020 or T5020 or Z5020 Tank Gauge.

The operation can be simple switching and Alarm. Volt free contacts (VFC) rated to 6 Amp 240 vac SPDT (Single Pole Double Throw) relays, set for possibly High High, High, Low , Low or High, Low and Water level, Bund level ? Pump Control is achieved by jumper selection to latch the pump connection output between Low and High.

Q/   Can we use any type of level switch input.

A/   Yes, if the switches are "simple aparatus" meaning reed switch or similar . (Not capacitance or resistance)

Q/  Can the system power a pump directly.

A/  No. The T4000 is a switch to operate the power to a pump. You may need to include a contactor in the circuit if the load is more than 6 to 8 amps.
