Omron H3YN-4 AC100-120 Electromechanical Timing Relay

Omron H3YN-4 AC100-120 is an electromechanical timing relay with a 100-120 VAC coil. It is designed to introduce a timed delay in electrical control circuits by delaying the relay output after the input becomes energized, enabling simple sequencing and delayed operation in automation tasks. The H3YN-4 designation identifies this specific timing relay model from Omron and it is suitable for use in industrial control panels and equipment where controlled timing between signals is required. By placing the device in a control circuit, technicians can achieve stepwise activation, interlock timing, or staged control without the need for solid-state timing components. The electromechanical nature provides a straightforward, replaceable timing solution within compatible systems that operate on standard AC control voltages. With a 100-120 VAC coil, it fits common AC control circuits found in many industrial settings, and its electromechanical relay mechanism delivers the timing function through a mechanical switching action tied to the input signal.
