What the ratings mean for fit
The H5S-WFB2D is a programmable multi-function time delay relay from the H5S series, running on a 24VDC supply. Its two SPST-NO (1 Form A) contacts each handle 15A at 250VAC — that's enough to directly switch small motor starters, solenoid valves, or contactor coils without an interposing relay. The delay range spans 1 minute to 1 week, set via up/down digit keys on the front face, with the timing initiated by applying input voltage. For a panel integrator: the DIN-rail clip and screw terminals mean it snaps into the same channel as a standard terminal block, no special bracket needed.
