Reliable control system DIL RC Series Control Relays and their respective modules can be flexibly control the completion of many tasks. As the basic unit, DIL RC series relay with 4 auxiliary contacts, the normally open contacts 4 and 3 normally open contacts and 1 NC contacts, 2 normally open contacts and 2 normally closed contacts. This relay can be used at the top of the installation and side-mounted auxiliary contact modules can constitute up to 8 auxiliary contacts. Pneumatic time delay module delay function, that is power and power-down delay function delay. Mechanical chain of modules even in the case of power failure to maintain contact device can be connected to the state. Coil module in the chain of action only when the contact device can be changed on-off state. This feature can effectively protect the park from the impact of the production process. Technical note: * solid structure; * Up to 8 contacts; ? The additional auxiliary contact parts of a pneumatic delay module can be installed or a mechanical linkage module.
