Excela - Electronic Switch


ABLE are exclusive distributors and suppliers of the new Excela from United Electric, the first switch of its kind. Designed to give plant operators an affordable way to upgrade to electronic performance, Excela has only two wires, so it can be easily dropped in to existing mechanical switch infrastructure. In fact, this innovative, high-quality electronic pressure and temperature switch delivers everything operators need for better performance at an affordable price.

Excela is especially relevant for industrial plant upgrades, offering ease of maintenance and accompanying low costs, electronic switches can be installed in existing two-wire mechanical switch infrastructure. Upgrades to ruggedly reliable and state-of-the-art technology are simple, swift and inexpensive. Unlike other options, which necessitate the reprogramming of set points or other adjustments making the transition complicated and costly, electronic switches offer an easy alternative.
