Digital Flow Switch (Integrated display type)

Circuit (of class 2) which is of maximum 30 Vrms (42.4 V peak) or less, with UL 1310 class 2 power supply unit or UL 1585 class 2 transformer. The product is a UL approved product only if it has a mark on the body. Use the specified voltage. Otherwise failure or malfunction can result. Insufficient supply voltage may not drive a load due to a voltage drop inside the product.

Digital Pressure Switch

Normal output Reversed output P_1 = A (A B)/4 n_1 = B + (A B)/4 A = Maximum pressure H_1 = (A B)/2 H_1 = (A B)/2 B = Minimum pressure In the OUT2 setting, the above P_1, n_1 and H_1 will be P_2, n_2 and H_2 respectively.
