Product Details Introduction

L911349010CB Relay Board Product Features 

L911349010CB is an industrial grade high reliability relay board designed specifically for power control and automation circuit switching, suitable for scenarios such as building power distribution, metallurgy and petrochemicals, and fire protection systems. Its core features are as follows:

1. Multiple contact output configuration

Equipped with multiple single pole double throw (SPDT) contacts, each containing normally open (NO)/normally closed (NC) contacts, with a rated contact capacity of 2A@250VAC It can flexibly drive various loads.

2. CB level protection performance

Integrated CB level overcurrent release, the main contact can connect and disconnect short-circuit current, with overload and short-circuit protection functions, suitable for the safety requirements of dual power switching circuits.

3. Wide voltage adaptive power supply

Supports AC220V ± 10% wide voltage input, compatible with 50/60Hz power frequency, voltage fluctuation range of 0.8-1.1 times rated value, suitable for industrial power grid fluctuations.

4. Strengthen electrical isolation

The contact and control side adopt photoelectric isolation design, with an isolation voltage of 2500VAC, and each terminal can withstand 2000VAC to the shell, eliminating circuit interference and leakage risks.

5. Quick response actions

Relay closing time ≤ 10ms, release time ≤ 5ms, dual power switching response time 1-2s, can quickly respond to control signals and fault switching requirements.

6. Strong anti-interference ability

Adopting EMC filtering technology and complying with DL478-92 anti-interference standard, it can resist electromagnetic radiation and power supply jitter in industrial environments, ensuring signal stability.

7. Status indication function

Equipped with power supply and contact action status indicator lights, it intuitively displays the working status and synchronously alarms in case of faults, facilitating on-site debugging and troubleshooting.

8. Long term stable lifespan

Mechanical lifespan ≥ 10 million cycles, electrical lifespan ≥ 100000 cycles (under rated load), contact resistance to arc and oxidation, and adaptability to frequent switching conditions.
