Electric Relay Control Unit – 90-EC1-A

Request Information

The 90-EC1-A Electric Relay Control Unit teaches electric relay control of electric motor and pneumatic systems and their industry applications. Students will learn industry-relevant skills related to these new topics including operation, installation, performance analysis, and design.

The 90-EC1-A provides students with the components to set up a variety of industrial relay control circuits using ladder diagrams and Boolean logic. Relay control is a fundamental building block in the study of automation because programmable controllers and solid-state controls also use the same programming methods.

The model 90-EC1-A includes a bench top-mount workstation console with electric relay control components, reversible electric motor, electro-pneumatic actuators, lead set, 24VDC power supply, student learning materials for both theory and lab, and teacher’s guide.

Components are pre-mounted to panels and include plug-in jacks to enable students to quickly set up circuits. Components can also be interfaced to external systems such as Amatrol’s 90-CT1 Computer Control 1 Unit for more advanced study.
