Suzhou Handa indistrial Automation China HT-413A P/N 1407003 AC 220V
The Suzhou Handa HT-413A is a robust and reliable safety relay module designed to enhance the operational safety of industrial machinery and automated systems. Manufactured by Suzhou Handa Industrial Automation in China, this module is a critical component for implementing safety functions such as Emergency Stop (E-Stop), Safety Gate Monitoring, and Two-Hand Control.
With a standard operating voltage of AC 220V and a contact configuration of 4 Normally Open (NO) and 2 Normally Closed (NC), the HT-413A (Part Number 1407003) ensures fail-safe operation, helping you comply with international machinery safety standards.
Key Features
-
High Reliability Safety Circuit:Â Features forced-guided contacts (mechanically linked) to prevent contact welding and ensure safe state in case of a fault, a fundamental requirement for safety relays.
-
Wide Operating Voltage: Compatible with AC 220V control systems, common in industrial environments worldwide.
-
Clear Status Indication:Â Equipped with LED indicators to provide visual feedback on the power and reset status, simplifying troubleshooting and operation.
-
Robust Contact Configuration:Â 4 NO + 2 NCÂ contacts offer flexible integration into various safety and control circuits, allowing for the direct control of contactors or the signaling of the safety status to a PLC.
-
Manual Reset Function:Â Requires a manual reset after a safety trip, ensuring the machine operator acknowledges the fault and intentionally restarts the system, preventing automatic and potentially hazardous restarts.
-
DIN Rail Mountable:Â Easy and quick installation on standard 35mm DIN rails, saving panel space and simplifying wiring.
