Transio A52/53 Entry-Level RS-232 to RS-422/485 Converters ADDC™ (Automatic Data Direction Control) RS-485 data control Auto baudrate sensing RS-422 hardware flow control: CTS, RTS signals LED indicators for power and signal states RS-485 multidrop operation, up to 32 nodes 25 KV ESD surge protection 2 KV isolation protection (A53) Built-in 120 Ω termination resistors The Transio A52 and A53 are smart RS-232 to RS-422/485 bi-directional converters that come with all of the great technical specs that Moxa is known for. This includes data direction control built into the hardware for both the RS-422 and RS-485 interfaces, LED indicators for power and signal states, and surge protection and isolation protection. The last two features take care of some of the major problems faced by serial communication connections in industrial environments. • Serial Communication RS-232 Signals Tx, Rx, DTR, DSR, RTS, CTS, DCD, GND (RJ45) RS-422/485 Signals Supports RS-422, 2-wire RS-485 (DIP switch selectable) Supports 4-wire RS-422, up to 10 nodes, 1.2 km with RTS, CTS Supports 2-wire RS-485, up to 32 nodes, 1.2 km Optical Isolation Protection 2 KV (A53), power/signal Power EFT/Surge Protecction 25 KV ESD surge protection • RS-422/485 Side RS-485 Data Direction Control ADDC™ • Serial Transmission Baudrate 50 bps to 230.4 Kbps • Physical Characteristics Housing ABS Weight 85 ± 5 g Dimensions 90 x 60 x 21 mm • Environmental Limits Operating Temperature 0 to 55°C (32 to 131°F) Operating Humidity 5 to 95% RH Storage Temperature -20 to 75°C (-4 to 167°F) • Power Requirements Input Voltage 9 to 30 VDC, 350 mA Power Consumption A52: 170 mA @ 9 V A53: 285 mA @ 9 V Over Current Protection Protection against 2 signals shorted together • Regulatory Approvals CE Class A FCC Class A • Warranty Warranty Period 5 years
