8520-3S5A-BAT-EX4-S-1-2-3-5-7

The 8520-3S5A-BAT-EX4-S-1-2-3-5-7 9/440 Resolver Based CNC System Module by Allen-Bradley, is a 5kW, resolver-based CNC system module, with 3-axis capacity, and 2 closed-loop analog output systems, which incorporates digital drive system with the CNC control in a single unit. It is designed to interface with 1326 servo motors, and it provides high machine performance, in a compact and a cost-effective package. The 8520-3S5A-BAT-EX4-S-1-2-3-5-7 has a processor board that provides logic control, and a feedback board that provides excitation power to the resolver attached to the 1326 servo motors. It also has a 3-resolver feedback port, with a single encoder feedback port, and it can support up to 3 Axis modules which convert supplied system DC power to variable 380 to 460 Volts AC voltage which controls the phase, amplitude, and the frequency for regulating the speed, the torque, and the direction of interfaced servo motors. The 8520-3S5A-BAT-EX4-S-1-2-3-5-7 has an operating voltage range of 324 to 528 Volts AC (3-phase) at 50 to 60 Hertz, with an operating current of 6.5A, and it comes with a power output of 5kW. The system’s processor board houses the CPU, and it provides a direct connection to the fiber-optic ring, E-Stop string and to peripheral devices.

The 8520-3S5A-BAT-EX4-S-1-2-3-5-7 communicates using the RS-233 serial interface ports (labeled A and B) that are configured for RS-232 communication and for transmitting data to and from the connected peripheral devices, and the system has integral remote I/O circuitry on the wiring board for remote I/O connection. The 8520-3S5A-BAT-EX4-S-1-2-3-5-7 has 2 resolver-based analog outputs (TB2 and TB3) on the wiring board, and it provides system backups via a charged supercapacitor on the processor board for if the power fails, and the backup time can be extended by up to 3 years with a lithium battery pack. It has 24 Volt DC Logic power that operates the processor, the axis module, and the resolver/encoder by using a 120 to 240 Volt AC input transformer at 50 to 60 Hertz, and its OFF/ON switch is regulated by using an OFF/ON control assembly. The 8520-3S5A-BAT-EX4-S-1-2-3-5-7 has LED indicators on the front panel which show the system’s operational status, and it is designed for optimal operation at an altitude of 1000m without derating. It has a working temperature range between 23 and 122 degrees Fahrenheit, at 5 to 95% non-condensing relative humidity, and it has a storage temperature range between -40 and 158 degrees Celsius. The 8520-3S5A-BAT-EX4-S-1-2-3-5-7 is UL, CSA, and CE certified and it weighs about 10.68Kg and has shipping dimensions of 400 x 150 x 280 millimeters.
