Crestron MC4-I – 4-Series Control System, International

Product Overview

The Crestron MC4-I is a compact 4-Series control system designed for international commercial and residential deployments. It functions as a mid-range automation controller supporting Cresnet, infiNET EX wireless, RS-232, IR, relays, and Versiport I/O. PoE-powered and compatible with 100/1000 Mbps networks, it is an efficient choice for integrators deploying Crestron automation outside the United States where international regulatory certifications are required.

Product Description

The MC4-I shares the same compact form factor as the MC4-R, fitting into structured wiring enclosures, DIN rail mounting kits, or standalone surface installation. Its infiNET EX 2.4 GHz wireless module communicates with keypads, sensors, and shades within a 50 ft range. Four IR outputs support legacy AV device control, while two relays and two Versiport I/O ports extend control to motorized equipment and analog sensors. BACnet/IP support allows integration with building management systems in light commercial applications.

Frequently Asked Questions

Q: What makes the MC4-I different from the MC4-R?
A: The MC4-I is configured for commercial and international deployments with CE regulatory certification and Crestron's standard commercial control platform. The MC4-R runs Crestron Home OS and is designed for residential automation dealers.

Q: Does the MC4-I support Crestron Home OS?
A: No. The MC4-I runs the standard 4-Series commercial Crestron control platform, programmed via SIMPL or Crestron Studio. For Crestron Home OS deployments, the MC4-R is the appropriate model.

Q: Can the MC4-I be powered without a PoE switch?
A: A PoE injector (802.3at or 802.3af) can be used if a PoE-capable switch is not available. No separate AC power supply is required.
