The 166C24 is a 2.04 VA power transformer that converts a 115 V, 60 Hz single primary into 24 V C.T. at 0.085 A (85 mA). It is a compact option for 24 V control, relay and signal circuits in OEM equipment.
As a 166 Series part it uses an economical single-primary design, an open-style channel bracket for two-hole chassis mounting, and minimum 6 in long leads. The dual bobbin construction means no electrostatic shield is required. Windings use Class B insulation (130 degrees C) for extra protection, although the design is UL listed as a Class A (105 degrees C) design, and each unit is Hi-Pot tested at 2,000 V RMS. The 166C24 drawing shows black primary leads and green secondary leads with a green/yellow lead on the secondary side.
Overall size is 2.06 in (52.3 mm) by 1.38 in (35.1 mm) by 1.19 in (30.2 mm), with 1.75 in (44.5 mm) between mounting holes and 0.187 in (4.7 mm) holes. Shipping weight is 0.3 lbs (0.14 kg).
