MRC 50 NO LONGER AVAILABLE - **USE MRC 55 AS NEW CONTROLLER**
FUNCTIONALITY OF MRC50E-100 MULTIFUNCTION CONTROLLER
The MRC50 controller is a microprocessor controlled multifunction unit. The control voltage is
rated maximum 24v @1A. The controller has 8 inputs [IN1 through IN8 (24vDC)] and 4
potential free Normally Open relay outputs [K1 through K4].
The controller is also equipped with four RS232 COM ports [COM1 through COM4] for
communication with the display and ticket mechanism. Programming of the MRC50 controller
is performed using the four color-coded programming buttons. The buttons are used to
configure a variety of controller options allowing the MEC70 Entry Station to be individually
configured for a high variety of installation requirements. The user can view the different
settings in real-time on the LCD display located on the front of the MEC70 housing.
For security, reason the MRC50 controller is not accessible from the access door. The MRC
50 controller is located below the top hood and is covered by a protective housing, which
allows authorized users to change the settings using the exposed programming buttons (see
pictures above for exact location, page 11). In order to hard wire the MEC, it comes with a set
of input and output terminals located in the base housing. In order to access those terminals
another protective cover has to be removed (see picture page 10). The terminals are
numbered and represent the exact same inputs and outputs as the MRC50.
