• Conductivity and Float Switch Controller
• Input types: Adjustable probe conductivity from 1 - 100K Ohms Input voltage: 120V AC
• Switches Contacts: Form C - SPDT (Single Pole, Double Throw)
• Contact Ratings: 10 Amp @ 120V AC (1/5 HP max.), 10 Amp @ 30V DC
• Temperature (Operating) -4° to 140°F / -20° to 60°C

The R2-120 is easily configured for two-level differential, single-point protection, or alarm operations, and can be set for pump-up (fill) or pump-down (drain) automatic dual-level control. The controller can be set for high - low liquid level control for conductive liquids with three conductivity probes.

Conductive liquid is sensed between each search and ground (standard). The controller is also equipped with a sensitivity adjustment to eliminate false actuations in some liquids or foams and can be adjusted to sense between 1K - 100K Ohms. An accessible view on-board LED on top of the controller indicates the on-off state to output contacts and controller status.
