The device maintains stable performance across a broad temperature range, ensuring that switching operations remain accurate and reliable regardless of environmental fluctuations.
Suitable for
Industrial automation control panels
Motor starter assemblies
Relay logic systems
Electrical signaling and monitoring circuits
When it may not be suitable
This contact block is specifically designed for 24V DC control circuits and is not suitable for direct connection to high-voltage AC power lines or applications requiring different voltage ratings. It should not be used in environments that exceed the specified operating temperature range or in conditions where extreme moisture or corrosive agents are present without appropriate protective enclosures.
Key specifications
Contact configuration: 2 NO + 2 NC
Control circuit voltage: 24V DC
Rated insulation voltage: 690V
Operating temperature range: -25 to 50 °C
Mounting type: Front mounting
How to use
The contact block is designed to be mounted onto compatible contactors or control relays. Ensure the power supply is disconnected before installation to prevent electrical hazards. Align the block with the mounting interface on the host device and secure it firmly according to the manufacturer's mechanical guidelines. Once installed, connect the control wires to the designated terminals, ensuring that the wiring matches the intended logic of your control system. After installation, perform a functional test to verify that the contacts actuate correctly when the coil is energized.
What to consider before purchase
Verify the voltage compatibility of your existing control system.
Ensure the contact configuration (2NO+2NC) meets your specific logic requirements.
Check the physical space available in your control panel for mounting.
Confirm compatibility with your specific contactor or relay model series.
Usage recommendations
Always ensure that the electrical load connected to the auxiliary contacts does not exceed the rated operational current to prevent premature wear or contact welding. Regular inspection of terminal connections is recommended to maintain optimal electrical conductivity.
