Usage area
The module, which is intended for installation in the motor terminal box, is used to convert HTL or TTL
signals into complementary signals with RS422 levels. With this form of signal, the probability of errors
in data transmission is considerably reduced. Use of this module is recommended for cable lengths in
excess of 30 m.
