继电器模组有哪些优势： 

1.继电器模组是把电气控制柜中的单个小功率继电器加以集成化、系列化，减少了中间接线环节，提高了产品的性能。产品顺应了微型化，集成化的发展趋势，是原单个继电器的更新换代产品。另产品可根据不同的数控系统而设计，更能适应现代数控机床的需要；

2.安装形式采用通用的35mmU型导轨安装，安装方便、快捷；

3.产品采用继电器为电磁式继电器日本和泉厂家，接线端子及支架为中国台湾进联厂家，精工制造；

4.每路加有动作指示灯；继电器线圈两端加有续流保护二极管；继电器的触点保护可选二极管保护电路、快熔保险及阻容吸收；标准型继电器模组现为4/8/12/16位继电器模组，1常开1常闭和2常开2常闭的输出规格。

What are the advantages of the relay module:

1. The relay module integrates and serializes a single small power relay in the electrical control cabinet, which reduces the intermediate wiring link and improves the performance of the product. The product conforms to the trend of miniaturization and integration, and is the replacement product of the original single relay. The other products can be designed according to different CNC systems, and can better meet the needs of modern CNC machine tools;

2. The installation form is installed by universal 35mm U-shaped rail, which is convenient and quick to install.

3. The product adopts the relay as the electromagnetic relay manufacturer of Japan and the spring, the terminal block and the bracket are Taiwanese joint manufacturers, and are manufactured by Seiko;

4. Each channel is equipped with an action indicator; a freewheeling protection diode is added to both ends of the relay coil; the contact protection of the relay is optional diode protection circuit, fast-fuse insurance and RC absorption; the standard relay module is now 4/8 /12/16-bit relay module, 1 normally open 1 normally closed and 2 normally open 2 normally closed output specifications.
