The Black Box ICD100A is an external, DIN-rail RS-232-to-RS-422/RS-485 converter for industrial and control-system installers who need to connect serial equipment over cable runs up to 4,000 ft.
Recommended For
- Industrial controls technicians connecting an RS-232 workstation or controller to RS-422/RS-485 equipment—such as time clocks, scales, or conveyor systems—over a longer cable run.
- Panel builders and maintenance teams installing serial conversion inside a control cabinet; the ICD100A is designed for DIN-rail mounting and accepts 10–30 VDC power.
- Installers extending an asynchronous RS-232 connection onto an RS-422/RS-485 link where optical isolation and surge suppression on the field-side lines are useful design requirements.
- Users integrating compatible serial devices over RS-485 who need two-wire half-duplex or four-wire full-duplex operation and can configure the unit’s onboard switches.
