Example: 61F-G [110/220 VAC] Desired supply voltage 2. If you order with a standard model number, the corresponding Relay Units are also delivered as part of a set. If you order the 61F-G, one 61F-11 Relay Unit is included in the set. - Page 3 8 VAC InterElectrode current Approx. 1 mA AC max. Power consumption 61F-G@: 3.5 VA max.; G1F-G1@, G1F-G2@, or G1F-I@: 5.5 VA max.; G1F-G3@: 7.5 VA max.; G1F-G4@: 14.5 VA max. InterElectrode operate 0 to approx. 4 kΩ 0 to approx. 5 kΩ 0 to approx.
- Page 4 61F-G@ Internal Circuit Diagrams The schematic diagrams shown below typify the internal connections of the various 61F models. The designations Ta, Tb, and Tc (sometimes referred to collectively as “U”) may occur more than once in a product, however, the “a” terminal is always an NO contact, a “b” terminal is an NC contact, and the “c”...
- Page 5 61F-G@ Note: The 61F11H relay deenergizes when there is water present across the Electrodes, whereas the 61F relay energizes when there is water present across the Electrodes. Also, the terminal connections of those Controllers provided with LED indicators differ from those which have no indicators.
