Internal Product Review
The 800-262 is a Copley Controls DC servo amplifier with 3 kHz current-mode bandwidth and a 25 kHz PWM frequency. A ±20 V reference input and 100 kOhm input resistance support stable command interfacing in precision motion systems. Dependable protection is reinforced by undervoltage shutdown below 22 V, making the unit a strong fit for tightly controlled servo applications.

Product Description:
The 800-262 is a single-axis DC servo amplifier produced by Copley Controls within the DC Servo Amplifiers series. The device translates command voltages from a motion controller into controlled armature current, enabling precise speed and position regulation of brushed DC motors used on pick-and-place modules, index tables, and similar automation axes. Its open-frame layout, low mass, and card dimensions allow the board to slide into drive chassis without consuming excess panel space.
In operation, the board supplies an auxiliary rail of ±5 VDC at ±5 mA for encoder or resolver electronics, eliminating the need for separate reference supplies. Command processing is supported by a 3 kHz current-mode bandwidth that accommodates low-inertia loads, while voltage-mode response is limited to 200 Hz for stable armature control when current feedback is disabled. A pulse-width modulation stage switching at 25 kHz minimizes audible noise and eases output filtering. The reference input has an impedance of 100 kΩ, allowing position controllers to drive the amplifier without noticeable loading. Protection logic resets the drive after faults and enforces a 50 ms recovery interval. A 5-pin power connector routes the DC bus and motor outputs, while a 16-pin signal header carries reference, feedback, and logic lines.
The amplifier accommodates command excursions up to ±20 V and recognizes digital enable signals once the control line exceeds 2.5 V. Thermal monitoring removes the drive output if the heat sink temperature reaches 70 °C, and an input supply monitor initiates shutdown whenever the bus drops below 22 V. The printed circuit assembly measures 1.37 inches high, 3.28 inches wide, and 5.10 inches long, allowing multiple modules to fit in confined cabinets. Its compact dimensions also permit short connections between the high-current output stage and the low-level control circuitry.
