Overview

The Multibus Converter is an industrial-grade isolated converter that supports USB / RS232 / TTL to RS232 / 485 / TTL, with built-in power supply isolation, digital isolation, and protection circuits like TVS diode. It is easy to use and suitable for industrial control equipment and/or applications with high communication requirements.

Feature

• Adopts original FT232RL for USB communication, fast communicating, stable and reliable, better compatibility
• Onboard over-voltage, over-current protection circuits (there's no protection between the two power supplies of the host terminal)
• Onboard unibody power supply isolation, providing stable isolated voltage, no extra power supply required for the isolated terminal
• Onboard unibody digital isolation, for isolating the signal, reliable and jam proof, low power consumption
• Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning proof & anti-electrostatic
• Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance
• Onboard TTL serial port 3.3V and 5V voltage level switch, allows the user to select TTL level of the Group B terminal
• Aluminium alloy enclosure with oxidation dull-polish surface, solid and durable

Specification

Note

 

A pad for 120R terminal resistor is reserved for the RS485 port, users can add the resistor to the begin/terminal devices if connect multiple devices.
