Liquid Level Controller
Level Controller for liquids in tanks. Switching-on relay in high level and switching-off in low-level values. When high level probes are submerged in liquid, a high-level indicator D7 goes on and this will result in initiation of P1 relay and LED D10 will light. Identically, intermediate level probes are also submerged in the liquid. The relay P1 will be on even when high-level probes are not submerged in the liquid. When the liquid level becomes lower than the intermediate level probes, a low-level LED D9 will light. This will result in tripping of relay P1. Power supply: 10~16V/100mA Low-level indicator. Intermediate-level indicator. High-level indicator. Relay-On
