The ATC 305E-101-A-10-PX Electronic Timer Relay is a plug-in timing module from ATC Automatic Timing & Controls featuring a SPDT (single‑pole, double‑throw) output and a 120 V AC coil. It supports both on‑delay and off‑delay operation, allowing a load to be energized after a set interval or held off for a defined period before switching. With 16 selectable timing ranges, this timer can be configured for a 120‑second interval as part of the 305E family’s standard options, enabling precise sequencing in automation tasks. Designed for use in compatible timer bases, it provides a compact, reliable timing solution suitable for basic automation timing needs in industrial control circuits.
