I/O Expander MCX4D Roger

The Roger MCX4D is a compact I/O expander designed for access control systems. It provides 4 digital inputs and 4 relay outputs, allowing you to monitor door contacts, request-to-exit buttons, and control electric locks or other devices. Communication is via RS485 bus, enabling integration with Roger access controllers and third-party systems.

With a wide power supply range of 12-24V AC/DC and DIN rail mounting, the MCX4D is easy to install in standard electrical cabinets. Each input can be configured as normally open or normally closed, and each relay output supports up to 2A at 30VDC. The device is ideal for expanding I/O capacity in medium-sized installations.
