The MR-J2CN3TM is a Mitsubishi maintenance junction card. It is used to connect a MELSERVO-J2 super series servo amplifier to a computer and to multiple analog monitors at the same time. The card is also used to enable an EM1 or emergency stop function when operators use a computer to run the test operation mode on the servo amplifier. An electromagnetic brake interlock can also interface with the servo through the MR-J2CN3TM maintenance junction card. The card connects to the servo amplifier through a MR-J2BUS bus cable. It connects to the computer through a standard communication cable. The ambient specifications for the MR-J2CN3TM card are the same as those for the compatible servo amplifiers. The operating temperature range is 32 to 131 degrees Fahrenheit (non-freezing). The storage temperature range is -4 to 149 degrees Fahrenheit (non-freezing). For both storage and regular operation, the relative humidity level in the atmosphere around the MR-J2CN3TM card should not exceed 90%. The location where the MR-J2CN3TM card is installed should be free of liquids, corrosive gasses, dirt, dust, flammable gasses, and oil mist. Operators must also protect the device from direct sunlight. The elevation of the site used where the MR-J2CN3TM card is installed and used should not be more than 1000 meters or 3280 feet above sea level. The weight of the MR-J2CN3TM card is 110 grams, and the dimensions of the card are 100 x 41.5 x 75 millimeters. There are 2 mounting holes on the MR-J2CN3TM maintenance junction card, and each mounting hole has a diameter of 5.3 millimeters.
