DIN rail mount asymmetric and symmetric cycle timer Right-Left / Up-Down / Forward-Backward / Inversor relay, DPDT, TENSE (Made in Turkey)

The ERS-07 by Tense Electronics is an Asymmetric Cyclic Right-Left (Inversor) Relay. It is designed to control two independent loads sequentially, commonly used for reversing electric motors or managing directional movements (e.g., "left-right," "up-down," "forward-backward"). 

Key Technical Specifications 

• Operating Voltage: 150V – 260V AC.
• Time Ranges: Highly adjustable between 0.1 seconds and 100 minutes. Older or specific variants may list steps like 10s, 100s, 10m, or 100m.
• Contact Capacity: 5A / 250V AC (Resistive Load).
• Mounting: Standard DIN rail or panel mount.
• Indicators: Features LED indicators for Left, Right, and Off (waiting) states. 

Operating Principle (The Cycle) 

The relay operates in a continuous loop as long as power is supplied: 

1. Work (Left/Right 1): The first load is activated for the set duration (Time 1).
2. Wait (Off): Both loads are deactivated for a set interval (Time 2) to allow for safe switching/deceleration.
3. Work (Left/Right 2): The second load is activated for the set duration (Time 1).
4. Wait (Off): Both loads are deactivated again for the set interval (Time 2) before the cycle repeats. 

Common Applications 

• Industrial Automation: Conveyor belts, mixers, and motor reversing systems.
• Agriculture: Irrigation systems in greenhouses.
• Commercial: Pool automation, advertising signage, and amusement park rides.
