Allen-Bradley 2080-MOT-HSC 250 kHz Counter Plug-in
Description
A 250 kHz encoder counter that adds PTO feedback to Micro800
The Allen-Bradley 2080-MOT-HSC is a high-speed counter plug-in with one quadrature (ABZ) differential input, up to 250 kHz, and 48-bit maximum count. The manual says it supports the same functions as the embedded counters on Micro800 controllers, but is enhanced for 250 kHz operation with a 5V differential line driver for better noise immunity, plus additional dedicated I/O.
Compared with the embedded counter, which is limited to 100 kHz and 12/24V inputs, the plug-in supports 5V differential line-driver encoders, embedded rate calculation (per pulse and cyclic methods), and one 5/24V output.

Three ways to use it
The manual gives three configurations: the High Speed Counter instructions (which also give PLS functions), a feedback axis linked to the PTO motion function for closed-loop control, and the user-defined function blocks RA_HSCPlugIn, RA_EncoderFDBK and RA_ServoFDBK for programmatic control.
One caution from the manual is that high and low preset status does not reset automatically with this module, unlike the embedded counter, so the program must clear it.
Typical uses are measuring conveyor or pump shaft speed with an incremental encoder, positioning with a servo drive that provides encoder feedback, and replacing an embedded 100 kHz counter where the encoder cable is long or electrically noisy. The operating range is minus 20 to 65 C, and the module is rated 2 G vibration from 10 to 500 Hz.
Wiring and capacity
The input is a differential quadrature input; minimum pulse width is 2 microseconds and phase separation 500 ns. Output current per point is 0.5 A and the signal exchange delay 2 ms. Of the 16 outputs, one is physical and 15 are virtual.
The module is 31.5 mm wide, 62 mm high and 20 mm deep. It draws 60 mA at 3.3V from the controller bus. A Kinetix 5100 wiring example is shown in the manual for encoder feedback applications. The manual lists plug-in slot counts of 2 for Micro820, 2, 3 or 5 for Micro830 (10/16, 24 and 48 point), 3 or 5 for Micro850 (24 and 48 point) and 3 for Micro870, while Micro810 has none.

About brand
Allen-Bradley is the brand of Rockwell Automation for industrial control: ControlLogix and CompactLogix controllers, I/O systems, PanelView operator terminals, PowerFlex drives, motor control and industrial network equipment. The company began in Milwaukee in 1903, when Lynde Bradley and Dr. Stanton Allen formed the Compression Rheostat Company to make the motor speed controller Bradley had invented in 1901. It took the name Allen-Bradley in 1909 and was bought by Rockwell International in 1985. Since 2001 its owner has been Rockwell Automation, which is still headquartered in Milwaukee, Wisconsin.

Milestones
- 1901: Lynde Bradley invents the compression rheostat to control the speed of electric motors.
- 1903: The Compression Rheostat Company is formed in Milwaukee with an initial investment of USD 1,000.
- 1904: Harry Bradley joins; a crane controller is shown at the St. Louis World's Fair.

- 1985: Rockwell International acquires Allen-Bradley.
- 2001: Rockwell Automation becomes the company's name; the Allen-Bradley brand marks 100 years in 2003.
Reading Allen-Bradley catalogue numbers
The first digits of an Allen-Bradley catalogue number identify the platform, which tells you what is compatible with what. 1756 is ControlLogix (chassis-based, used for large process and plant control), 1769 is CompactLogix 5370 with Compact I/O, 5069 is CompactLogix 5380 with Compact 5000 I/O, 1734 is POINT I/O, 1794 and 5094 are FLEX and FLEX 5000 distributed I/O, 1746 and 1747 belong to the older SLC 500 family, 1766 is MicroLogix 1400 and 2080 is Micro800. For drives, 25B is PowerFlex 525 and 22B is PowerFlex 40; in a code such as 25B-D010N114, "D" means 380–480 V, "010" is the output current rating, and N114 instead of N104 means the drive has an integrated EMC filter. Many plants in the region still run SLC 500 and older MicroLogix systems, which Rockwell has discontinued, so exact spares and migration to CompactLogix are both common requests.
Where Allen-Bradley products are used
In Oman and the GCC, Allen-Bradley controllers and drives run on oil and gas facilities, water treatment and pumping stations, cement, food and beverage and packaging plants, and on machines supplied by American OEMs. ControlLogix is often the platform for plant control systems, while PowerFlex drives are used on pumps, fans and conveyors.

Ordering Allen-Bradley products: what we need
Send the full catalogue number and the series letter from the label (for example 1756-EN2T Series D), because firmware and compatibility can change between series. For drives, add the motor power, voltage and filter option. For a discontinued SLC 500 or MicroLogix part, tell us whether you need the exact spare or a migration proposal.
