Usage area
The module, which is inten ded for installat ion in th e motor ter m inal box, is used t o convert H TL or TTL
signals into complementary signals with RS422 levels. With this form of signal, th e pr oba bi lity of errors
in data transmission is c onsiderab ly reduce d. Use of this m odule is rec omm ended for cable le ngths in
excess of 30 m.
