RS232 converter D1061S-077

RS422/RS485fieldbusrepeater

SINGLE CHANNEL RS 422 / RS 485 FIELD BUS ISOLATING REPEATER DESCRIPTION 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. FEATURES • Input/Output from Zone 0 (Zone 20), installation in Zone 2. • RS422 / RS485 Hazardous Area I.S. Signal. • RS232 / RS422 / RS485 Safe Area Signal. • Transmission speed up to 1.5 Mbit/s. • Three port isolation, Input/Output/Supply. • EMC Compatibility to EN61000-6-2, EN61000-6-4. • In-field programmability by DIP Switch. • High Reliability, SMD components. • Simplified installation using standard DIN Rail and plug-in terminal blocks. • 250 Vrms (Um) max. voltage allowed to the instruments associated with the barrier.
