The EP250 is a comprehensive training system for electronic control of pneumatic technology. This training system offers true electrical control and logic of pneumatic technology in a replicated manufacturing press/stamping and vise/clamping environment.

Electronic control is done through use of a Programmable Smart Relay Micro Controller. System components and hardware are mounted in a configuration to replicate manufacturing operations. Like a PLC, the Smart Relay allows the user to program and control up to eight inputs and four outputs simultaneously.

However, unlike a PLC, the simplified logic programming software that is included with the Smart Relay requires no previous PLC programming knowledge. This allows the student to focus on the learning objectives and controlling the pneumatic elements without having to study PLC programming first.

The EP250’s curriculum is designed to cover the background, use and application of electronic control of pneumatic components in an application-oriented setting. Our training system is accompanied by an instructor’s guide as well as a student manual. This manual is a comprehensive student resource, featuring detailed exercises and testing materials.
