Six timing functions in one DIN-rail package
The ABB 1SVR550029R8100 is a multi-function timing relay with six selectable operating modes, covering delays from 0.05 seconds up to 100 hours — enough range to handle everything from conveyor start sequencing to pump alternation cycles. Its single change-over SPDT contact (1 C/O) switches loads up to the relay's rated current, and the 24–240 V AC/DC universal coil means the same part works across control voltages common in both North American and European panels.
DIN-rail fit and panel integration
The compact single-pole housing leaves adjacent slots free for other control components in a crowded enclosure.
ABB lists this relay as current-production (lifecycle stage: current).
