The EM relay module MREL is the perfect USB solution for high-performance switching applications.
The 4 relays are designed to switch a maximum current of 5A (AC) (at 60V). 4 green LEDs indicate the switching status and the compact dimensions allow installation in the smallest space.
Like all EM I/O modules it fits on the module rail mounting of the products TB-M and
TB-H and can be fixed on this with a screw. It is with hardware of E.E.P.D. / EMTrust as well as with most x86-and ARM third-party hardware compatibly. In addition to the assembly in the module mounting it can be fixed to a hat rail. A variation with 80-cm-long USB cable (type A plug) is also available especially for it.
