Industrial RS232 to RS485 Converter

This industrial grade converter translates asynchronous RS232 signals into balanced differential RS485 signals. It supports bi-directional data flow between hosts, MCUs or peripherals. The module operates at baud rates from 300 to 115200bps. It is designed for point-to-point and point-to-multipoint networks.

ADI Magnetic Isolation 600W Anti-Surge

The adapter provides magnetic isolation to protect connected equipment from ground loops and voltage spikes. Embedded TVS diodes and lightningproof diodes absorb transient surges rated at 600W. This protection replaces basic non-isolated converters that leave serial ports exposed to industrial noise. The upgrade is worth it when cable runs cross noisy environments or span different power domains.

1.2 KM Transmission Distance

RS485 differential signalling enables stable communication up to 1200m at supported baud rates. The RS232 side remains limited to roughly 15m before signal degradation. Screw terminal and RJ45 connectors are provided for the RS485 port to suit different wiring practices. Three onboard LEDs indicate power, TX and RX activity for quick diagnostics.

Questions about this item

What connectors does the RS485 side of this converter provide?

The RS485 side provides both a screw terminal block and an RJ45 connector for flexible industrial wiring.

How is the converter powered and what indicates it is working?

The unit draws power from the RS232 port; three onboard LEDs show power, TX and RX activity to confirm operation.

What protection components may need replacement after a heavy surge event?

Embedded TVS diodes and lightning-proof diodes absorb transients; they are not user-replaceable, so the module would be swapped if damaged.
