RS-232 to RS-485/422 converter for industrial

The Black Box Corporation ICD400A converts RS-232 signals to RS-485 or RS-422 standards. It enables legacy serial equipment to communicate over longer distances in industrial environments. The unit suits engineers maintaining automation systems that rely on older serial interfaces.

DIN-rail mountable unit requiring external power

This converter fits onto a standard DIN rail inside a control cabinet. It needs an external power source to drive the RS-485/422 differential outputs. The design isolates the converted signals from the host RS-232 port, freeing the host from voltage-level mismatches.

Transparent conversion up to 485422 baud without

The ICD400A handles asynchronous data rates up to 485422 baud across the converted interface. It passes data transparently without interpreting higher-layer protocols. Throughput drops if the RS-232 source cannot sustain the selected baud rate or if cable length exceeds the electrical specification.

Questions about this item

How does the ICD400A handle continuous data conversion between RS-232 and RS-485/422 under sustained load?

The ICD400A is designed to convert signals between RS-232 and RS-485/422 interfaces for industrial communication links.

What are the noise, heat, or power characteristics of the ICD400A during all-day operation?

The converter operates without an internal fan, relying on passive heat dissipation through its metal housing during continuous use.

Which existing interfaces or cables must I already have to connect the ICD400A into my current setup?

You need an available RS-232 serial port on your host device and compatible RS-485 or RS-422 cabling for the field side.
