Programmable Logic Controller Trainer II

1. This trainer is mainly composed of training bench, control panel, mainframe module, simulation modules, three phase squirrel cage asynchronous motor, etc. 2. It adopts modular type structure, the experiment modules can be replaced easily, which is convenient for function expansion and new experiment development.

The PLC mainframe and experiment modules can not only be connected by self-locking type plug-in wires, but also by flat cable at a time. 3. The device is designed with ground protection and leakage protection functions. Sheathed connecting wires, insulated socket and heat resisting table top are adopted to ensure safety.
