MOXA Transio A53 | RS-232 to RS-422/485 Serial Converter | 2 kV Isolation

Тransio A53 (RS-232 / RS-422/485)

The MOXA Transio A53 is a smart, bi-directional serial converter engineered to provide reliable and stable conversion between RS-232 and RS-422/485 serial interfaces. Designed for industrial environments where communication stability is critical, this entry-level converter addresses major challenges such as ground loops and transient voltage surges with robust isolation and protection features .

Key Features and Product Highlights

• Multi-Interface Conversion: Provides bi-directional conversion between RS-232 and RS-422/485 serial standards, supporting RS-232, RS-422, RS-485 2-wire, and RS-485 4-wire operation for maximum application flexibility .

• 2 kV Optical Isolation (A53): Features 2 kV optical isolation protection that completely separates ground loops between connected devices, preventing damage caused by uneven ground voltages and ensuring reliable communication over long distances .

• 25 kV ESD Surge Protection: Built-in 25 kV ESD surge protection safeguards the converter against transient voltage surges from power lines, motors, or other electrostatic sources common in industrial environments .

• ADDC™ Automatic Data Direction Control: Proprietary ADDC™ (Automatic Data Direction Control) technology eliminates the need for manual switching of RS-485 data direction, simplifying installation and ensuring reliable half-duplex communication .

• Automatic Baudrate Detection: Automatically senses and adapts to the baudrate of connected devices, supporting transmission rates up to 0.9 Mbps for seamless integration with existing equipment .

• RS-422 Hardware Flow Control: Supports full RS-422 hardware flow control with CTS and RTS signals, enabling reliable communication with devices requiring flow control .

• RS-485 Multidrop Operation: Allows connection of up to 32 nodes in an RS-485 multidrop network, enabling flexible expansion of serial networks .

• Built-in 120Ω Termination Resistors: Integrated 120-ohm termination resistors simplify installation and ensure signal integrity on longer cable runs .

• LED Indicators for Status: Clear LED indicators display power and signal status (TxD, RxD) for immediate visual feedback on communication activity .
