I/O Relay Module Racks

1. What are I/O Relay Module Racks?

An I/O relay module is an electrically controlled switching device that uses an electromagnetic coil to actuate contacts to switch circuits on and off. Its core function is to convert low-current signals into high-current load control. It is commonly used in automation systems, industrial control, and embedded devices.

 

2. What are the Working Principles of I/O Relay Module Racks?  

Electromagnetic Induction Drive: When the coil is energized, it generates a magnetic field, attracting the armature, which drives the contacts, switching the circuit.

Isolation: Some modules utilize optocoupler isolation (e.g., with an isolation voltage of 1500V) to enhance system safety.

 

3. What are the Typical Parameters of I/O Relay Module Racks?

Operating Voltage: Commonly available options include 5V/12V/24V DC.

Load Capacity: Supports specifications such as 250V/10A.

Triggering Mode: Supports dry contact and NPN inputs.

 

4. What are the Application Scenarios of I/O Relay Module Racks?

Industrial Automation: Used for PLC control and sensor signal switching.

Communications: The modular design facilitates integration into systems such as switches and routers.

Redundancy: Parallel operation or hot backup improves system reliability.

 

5. Modular Expansion of I/O Relay Module Racks

Supports series and parallel expansion to meet varying voltage and current requirements.

Can be integrated with a cloud platform for remote monitoring, alarms, and data management.
