Conductive Level Controller 61F-D21T-V1 Ideal for level control for industrial facilities and equipment. Outputs can be set to self-hold at ON or OFF using self-holding circuits. Sensitivity adjustment of operating resistance from 10 to 100 k for application to a wide range of liquids. Delay timer to prevent relay contact chattering caused by waves. Models with a wide AC power supply range (100 to 240 VAC) and 24 VAC/DC reduce the number of level controller models kept in stock. CE marking, cUL recognized. Easy wiring with ferrules 2 2 2 2.5 mm solid or 2 1.5 mm standard ferrules. Model Number Structure Model Number Legend 61F- 123 1. Basic Model 61F: Conductive Level Controller 2.
