Roger MCX402-BRD Door Expander

MCX402-BRD is I/O expander dedicated to the RACS 5 system. Depending on uploaded firmware the expander operates with two Wiegand interface terminals or two PRT series terminals. After connection to MC16 controller the device enables to control single door. The expander operates with backup battery which can be charged with 0.3A current. MCX402-BRD expander is offered separately or as a component of MC402-1-KIT and MC402-2-KIT.

The expander can be supplied with 24VDC or 18VAC and in such scenario it offers 13.8VDC power supply outputs (AUX, TML) and backup battery charging. Alternatively the expander can be supplied with 12VDC but then it does not offer power supply outputs and battery charging. The expander charges backup battery with 300mA stabilized current up to 13.8V. Backup power supply is activated automatically in case of main powers supply shortage. If the voltage at backup battery drops below approx. 10V then the battery is automatically disconnected from expander and remains disconnected until mains power supply returns.

The communication method with MC16 access controller is provided with RS485 bus which can encompass up to 16 devices of RACS 5 system, each with unique address in range of 100-115.
