The SSAC TDR3A11 Time Delay Relay is an 11-pin plug‑in member of Littelfuse’s SSAC TDR family, combining digital timing with a 10 A isolated relay output for reliable control of loads in industrial automation. It accepts a wide input voltage range (12–230 V) and offers SPDT or DPDT contact configurations depending on the exact variant, with timing ranges spanning three scales and a repeat accuracy of about ±0.5%. The timing behavior provides configurable delays suitable for sequencing, interlocking, and safe startup/shutdown tasks on control panels.
