The 8520-CPUX is a CPU module, manufactured by Allen Bradley Inc. This Central Processing Unit belongs to the 9/260 series product line of modules by Allen Bradley. The 8520-CPUX board can be found with two alternative part numbers, which 90781002 for the revision 02, or 90781001 for the 01 revision.  With a weight of approximately 3 pounds (1.36 kilograms) and dimensions close to 16 x 11 x 3 inches (406.4 x 279.4 x 76.2 millimeters), this Industrial Control System unit is one member of a series of parts that are necessary for the functionality of a 9/260 type enclosure. This processing unit, the 8520-CPUX, should be paired with a Motherboard and the Main Power Supply (abbreviated PS1). All three of these units will have to be inserted into the 9/260 series enclosure housing. The enclosure for which this CPU is necessary is a type of enclosure that can support digital or analog servo modules. This enclosure also supports remote I/O ports and the main power supply. When installing all of the necessary components to operate the 9/260 (or 9/290) type enclosure, the motherboard unit should be installed first and attached to the rear enclosure wall. This CPU can then be inserted next to the motherboard and attached to it. This CPU board should be slid along the provided tracks when removing or inserting it, to ensure that it is installed or removed correctly. This board contains a green LED light which has various indication abilities and an RS-232 port (port A), both of which can be seen when viewing the module from its front view. (The port on this part is used for RS-232 type communications only). From the side, the user will be able to see this CPU’s high-speed shadow RAM, its EPPS Jumper, its Super Capacitor, and its Flash memory on SIMMA.

The Allen-Bradley 1785-LT4 is one version of the Classic 1785 PLC-5 Programmable Controller modules. The maximum analog I/O of this module is 512 and the program scan time is 2 ms (discrete logic) and 8 ms (typical). To optimize this scan time, divide the I/O rack between multiple channels. Place the most critical I/O on a single channel, and turn off the I/O on other channels. Because all I/O channels are independent, the remote I/O scan on one channel will not affect remote I/O scan on other channels. The Allen-Bradley 1785-LT4 has 1 DH+ port, the remote I/O transmission rate is 57.6 kbps, and the maximum user memory is 6K words. The Allen-Bradley 1785-LT4 is regarded as Industrial Equipment Class 1, Class A in accordance with Publication IEC/CISPR 11. Without appropriate precautions, there may be difficulties in ensuring electromagnetic compatibility in other environments due to conducted and radiated disturbances. The operating temperature of this module is from -25-60 °C (-13-140 °F). The nonoperating temperature of this module is from -40-85 °C (-40-185 °F). The relative humidity of the 1785-LT4 is from 5-95% without condensation. The operating vibration of this module is 2 g at 10-500 Hz. The Allen-Bradley 1785-LT4 has an operating shock of 30 g (3 pulses, 11 ms). The nonoperating shock of this module is 50 g (3 pulses, 11 ms). The 1785-LT4 has an ESD immunity of 4 kV contact discharges and 8 kV air discharges.

The Allen-Bradley 1785-ME64 is a PLC 5 Memory Device Module. The 1785-ME64 has a memory size of 64K words. The Maximum I/O Chassis Universal Remote of this module is 32 per I/O Link. The maximum number of analog I/O of this module is 3072. The Backplane Current of this module is 2.5 A at 5V DC. The Allen-Bradley 1785-ME64 can be used as a Backup module. This module comes with a Control Coprocessor Expansion Port. Remember to switch power off before removing or inserting this module. If you remove or install the module with the power switched on, an electrical arc may happen, and this electrical arc can cause injury and excessive wear to the contacts on the module and its mating connector. Worn contacts may create electrical resistance and this may reduce the product’s reliability.  The Allen-Bradley 1785-ME64 is an Electrically Erasable Programmable Read-Only Memory (EEPROM) module. This module is user-modifiable read-only memory (ROM) which can be erased and reprogrammed (written to) repeatedly through applications with a higher-than-normal power supply voltage. The operating temperature of the 1785-ME64 is 0-60 °C (32-140 °F) and the storage temperature is -40-85 °C (-40-185 °F). The relative humidity is 5-95% without condensation.

The trip unit includes either a fixed or an adjustable thermal element for inverse time delay on overload and an adjustable magnetic element for protection against short circuits. In open air at 40°C, a circuit breaker with the trip unit installed will carry continuously a current (Ith) equal to the ampere rating marked on the trip unit nameplate without exceeding a 50°C rise at the terminals. The National Electrical Code (USA) requirements state that enclosed overcurrent protective devices may be loaded to a maximum of 80 percent of the open air rating (Ith).

Reversing contactors are used primarily for reversing single- or three-phase motors in applications where running over current protection is either not required or is provided separately. They consist of two contactors mechanically and electrically interlocked to prevent line shorts and energization of both contactors simultaneously.
