Struthers-Dunn A45-010A Solid State Time Delay Relay

The Struthers-Dunn A45-010A Solid State Time Delay Relay is a solid-state timing device with a 24 VAC / 24 VDC coil, engineered to insert a defined delay into a control circuit after energization. The A45-010A combines a non-mechanical timing module with relay contacts to provide a timed transition between input energization and the subsequent circuit action, offering a compact option for automation and panel applications. With 24 VAC or 24 VDC coil compatibility, it accommodates common factory power and logic supplies, enabling integration into standard control architectures without specialized drivers. As part of Struthers‑Dunn’s long-running time-delay product family, the A45-010A is intended for use in sequencing, interlock routines, or startup delay scenarios where a predictable delay is required before a load changes state. The solid-state design reduces wear associated with mechanical timers and can offer repeatable timing performance under typical industrial conditions.
