R60B-45/S2-R60BLEADS

This page lists R60B-45/S2-R60BLEADS as an R60B fan delay board plus a wire harness, with a 1 second on delay, a 45 second off delay, and a 2.5 by 2.5 inch board. The R60B specification linked here describes a one-speed fan board for a line-voltage fan, powered by 24 Vac, with a 24 Vac thermostat fan signal. The fixed delays in that specification are 1 second on and 45 seconds off after G turns off. Thermostat R, C, and G connections are screw-in terminals, and the fan connections are quick connects on the relay.

Ratings in the specification are 18 to 30 Vac operation and fan outputs of 12 FLA (30 LRA) at 240 Vac. PCB material is CEM 1. Operating temperature is -40 F to 158 F, storage is -40 F to 185 F, and relay life is 100K cycles at full load. The board size in the specification is 2.5 by 2.5 inches, matching the size on this page. The separate R60B leads sheet, for the harness this page names, describes three colored leads used when female spade terminals are preferred over the on-board screw terminals.
