Smart Card Technology

The EMX4 smart card redefines the role of a soft starter. With the appropriate smart card installed, the EMX4 is able to operate as an entire system controller. 

EMX4_Smart Card_IMG_8045_cc_2_CMYK 1

Smart cards deliver industry or application specific functionality and are easily inserted into the EMX4, simplifying system design, installation and setup. By transforming your EMX4 with an industry specific smart card, your system can be purpose-built around one central point of intelligent control and communications.

Using this technology will improve the overall efficiency of your system, and put you firmly in control.

 

Soft Starter Model Selection

The EMX4 Series includes two soft starter models: The EMX4i is a full featured soft starter with ratings up to 1200A, while the ‘cost optimized’ EMX4e model provides limited features and ratings (up to 580A).

 

Troubleshooting

Troubleshooting soft start issues has never been easier!

Start Here — a free mobile app available for both iOS (App Store) and Android (Google Play) devices — puts the tools you need in the palm of your hand. Formerly known as Benshaw Pocket Technician, the Start Here app retrieves useful data from Benshaw EMX4i and EMX4e soft starters to help users identify, analyze and resolve common motor starting issues. If you need assistance with a soft start issue, the data retrieved can be shared with Benshaw’s technical support team at the click of a button.
