The DIN-Rail RS422 / RS485 Fieldbus Isolating Repeater type D1061S-077 is used to separate Intrinsically Safe RS422 / RS485 equipment located in Hazardous Area from a RS232 / RS422 / RS485 controller located in Safe Area. Transmission speed is DIP-switch adjustable from 1.2 Kbit/s up to 1.5 Mbit/s. Terminating impedance is DIP-switch selectable inside the unit (200 Ω value) for both sides of communication lines (Hazardous Area and Safe Area side). RS422 / RS485 connection in Safe Area is provided both on terminal block and SUB D 9 poles female connector on the unit. RS232 connection is provided on SUB D 9 poles female connector only. The module also provides a shield terminal block for connecting cable shielding on Hazardous Area side.Input/Output from Zone 0 (Zone 20), installation in Zone 2.RS422 / RS485 Hazardous Area I.S.
