2.1. Introduction
The USB-OPTOIN-X-RELAIS-X modules provide relays with a maximum
switching voltage of 36V DC (max. 1A, 15 watts) and Opto-in inputs, which
are suitable for industrial applications for registration of status or even to count the
changes of state of the inputs.
Our USB modules have been developed for industrial applications for
measurement, control and regulation. The modules all feature a USB interface and
can therefore be connected to PC systems with USB bus. The USB bus has been
used successfully for many years in use and is characterized by its high flexibility.
As terminal block, user-friendly terminal strips with locking protection and ejection
mechanism are used. They allow quick replugging . The wire connection itself is
realised with a screwless connector system. A tool is included with each module.
