The GT5Y-2SN1A200 is a single-function timer with blade plug-in contacts designed for industrial automation and control applications. It features delayed DPDT contact configuration rated at 5A, operates at 240 VAC, and provides four selectable time ranges (1 sec, 10 sec, 1 min, 10 min) with power-on trigger (maintained start signal) timing function. The timer delivers exceptional timing accuracy with a repeat error of ±0.2% maximum and includes Power ON and timing out LED indicators for operational visibility. Control settings are adjustable by hand or screwdriver, and the device uses the same sockets and hold-down clips as IDEC's RY4S and RU series relays, enabling seamless integration into existing relay-based control systems.
