1. Overview
The SS-94B series time relay is used for relay protection and automatic control of secondary circuits in power systems. As a delay element, it enables the controlled components to achieve the required delay, achieving selective coordination of protection and ensuring the safe and reliable operation of the power system.

2. Structural Features
The SS-94B series time relay adopts rigid A11K, A11H, A11Q housing, and the external dimensions and installation dimensions are shown in the appendix of this manual. The setting value can be easily changed, and the mountain pulling mechanism can be easily repaired. The setting value is adjusted using a digital dial and a crystal oscillator is used to reduce errors. Added a time compensation preset circuit, which has extremely high accuracy for extremely short delay values. Its principle diagram is shown in the figure
