Standstill and timer relays are safety devices used to monitor machine motion and manage time-based control functions in industrial automation systems. Standstill relays detect when machinery or equipment comes to a complete stop, triggering safety actions such as locking out power or initiating a shutdown process. Timer relays, on the other hand, manage delays or timing sequences, ensuring operations occur within specific time frames. Together, these relays ensure safe system operation, prevent accidental starts, and maintain precise timing in automated processes.
Key Features:
- Standstill Detection
 Monitors equipment to detect when it has stopped moving, preventing unintentional startup.
- Adjustable Time Settings
 Allows users to set specific time delays for machinery operation, shutdown, or other functions.
- Safety Lockout
 Ensures machinery cannot restart until safe conditions are met or the system timer has elapsed.
- Versatile Applications
 Can be configured for both standstill and timing functions, offering flexibility for different control needs.
- Reliability
 Designed for industrial environments with high resistance to vibrations, dust, and temperature fluctuations.
Applications:
- Machine Safety
 Prevents accidental startup by ensuring machines remain off after a stop or power failure.
- Conveyor Systems
 Ensures conveyor belts or material handling equipment remain in a safe state until the system confirms standstill or the timer completes.
- Automation Control
 Helps synchronize equipment operation and ensures processes occur in a safe, timely sequence.
- Motor and Pump Systems
 Manages start/stop sequences, preventing issues like overrun or failure to stop in mechanical systems.
Standstill and timer relays provide essential control and safety functions, improving operational reliability and ensuring equipment operates within specified time frames, minimizing risks in industrial environments.
