Maximum Controls Matrix III Control Board for Rhino Models

Genuine OEM Matrix III Control Board for MAX RHINO Industrial Gate Operators

The MXR is the genuine OEM Maximum Controls Matrix III control board for the MAX RHINO 4000 FS and MAX RHINO 5500 commercial and industrial brushless DC slide gate operators. Mounted inside the operator housing, the MXR drives the brushless DC motor, manages all gate-cycle logic, interfaces with safety sensors, accessory devices, and access control inputs, and provides the diagnostic and programming interface for the installation. The MXR is the correct factory-sourced replacement when the existing Matrix III board fails due to lightning damage, water intrusion, power surge, or extended service life.

Beyond standard motor control, the MXR carries 16-position ERD sensitivity adjustment for both opening and closing directions with independent motor overload monitoring, monitored UL 325 2018 entrapment protection inputs for both Normally Closed and 10K resistor-terminated sensors across Opening, Photo Close, and Open-Close channels, an integrated three-slot loop detector rack for Exit, Center, and Safety loops, and built-in maglock control with adjustable disengagement timing. The on-board LCD display and programming buttons walk the installer through date and time setup, mode configuration, and feature toggles. A USB OBD and Black Box port logs the last 8,000 events to any standard USB flash drive for download to a computer or smartphone, giving installers full event history for field diagnostics. Solar operation is supported natively through the POWER/SOLAR IN terminal with an on-board Solar Mode switch for off-grid installations.

Conclusion

The MXR is not interchangeable with the Matrix III boards used in other Maximum Controls PRO series operators. It is confirmed for use exclusively with the MAX RHINO 4000 FS and MAX RHINO 5500. The MAX RHINO 4000 FS is a Fail Safe operator that back-drives to open on loss of AC power or battery depletion; the MAX RHINO 5500 is a Fail Secure operator. Both are rated UL Class III and IV only. When replacing the board, inspect the motor wiring harness, limit sensor cables, entrapment protection devices, and accessory transformers for damage at the same time, as electrical faults in connected components are a common cause of board failure.
