Housing the device in flame-retardant ABS, we guarantee both safety and durability. Its wide humidity and temperature tolerances, robust electromagnetic relay, and high mechanical life are tailored for harsh conditions and extensive operational cycles.

FAQ's of Standstill Safety relay or Zero speed detector:

Q: How does the standstill safety relay detect zero speed in machinery?

A: The device uses a pulse counting/speed threshold method with a digital (pulse or sensor) input, monitoring the pulse frequency to determine if the machinery has come to a stop or is rotating below a set threshold.

Q: What types of output contacts does the zero speed detector provide?

A: It features relay contacts in both Normally Open (NO) and Normally Closed (NC) configurations, supporting control circuits with a 5A contact load at 250V AC.

Q: Where is this safety relay typically installed?

A: Installation is performed on a DIN rail within control panels near motors or machinery, ensuring quick response to standstill conditions in various industrial environments.

Q: When should I use this product in my automation system?

A: It is recommended for use in applications where detecting machinery stop or zero speed is essential, such as conveyor systems, hoists, or safety interlock mechanisms, to prevent accidental re-starts or equipment damage.

Q: What are the benefits of adjustable response time on this relay?

A: Adjustable response time (50 ms to 500 ms) allows customization based on machinery type and required safety margins, ensuring sensitive and reliable speed detection without false tripping.

Q: How are status indications provided on the device?

A: The relay includes dedicated LED indicators for power and output status, giving immediate visual feedback to operators regarding the device's operational state.

Q: What protections does the zero speed detector offer?

A: Built-in overvoltage and short circuit protection ensure device longevity and operational safety in fluctuating or demanding electrical environments.
