McLennan Operator Panel

Back Plane and Power Supply. The stepper drive system back plane allows the stepper drive power supply to be readily connected to two of the bipolar stepper drive cards and the programmable 2 axis control board. Connection is without the need to use a soldering iron enabling a complete system to be constructed in a minimum of time. The nature of construction of the back plane and power supply enable a very flexible single or 2 axis system to be produced. Only the 3.5A bipolar drive board is compatible with the back plane. The drives can be fed with external control signals or, by the addition of the programmable 2 axis control card a stand alone system can be produced catering for many applications. The whole system can be built into a standard 19in. wide by 3U high Euro Rack. All connections are made via screw terminals to the rear of the back plane. Suitable 19in. rack parts (as shown), that may be required for enclosing the drive systems are listed in the Enclosures section and have to be ordered separately.
