The Multi IO Extension 590 serves as a power-saving alternative to commercial standard coupling relays. The coupling relay is controlled as a mono-stable relay, but uses a bi-stable relay internally, thus reducing the holding current by up to 95%.
The Multi IO Extension 590 has an integrated fuse to protect high-quality equipment.
