The GT3W-A11D12N is an analog electronic timer designed for sequential and recycling timing control in industrial automation systems. It features a 12V DC rated voltage with recycler outputs in ON-start mode, providing a delayed SPDT contact rated at 5A for 120V AC or 30V DC resistive loads. The timer offers selectable operation modes including sequential start, on-delay with coarse and fine adjustment, recycler with instantaneous output, and interval timing functions, with a time range of 0.1 seconds to 6 hours. It includes external start, reset, and gate inputs for flexible control, along with power and output status indicating LEDs for operational visibility. The device is housed in an 8-pin configuration suitable for DIN rail or panel mounting, with mechanical life rated at 20,000,000 operations minimum and electrical life at 100,000 operations minimum under resistive load conditions.
