BTM-055-20 by Copley Controls

The Copley Controls BTM-055-20 amplifier is a compact member of the Bantam M-Axis Controllers series, designed for precision motor control in industrial automation. Delivering a peak current of 20 A DC and supporting an input voltage range of +12 to +55 V DC, this module ensures rapid response and high dynamic performance. Its use of digital Hall feedback from brushless motors underpins accurate position sensing and closed-loop control, making it ideal for applications that demand both speed and precision.

Featuring a continuous current rating of 10 A DC (±15 %) and a continuous output power of 523 W, the BTM-055-20 maintains reliable operation under sustained loads. It offers a peak output power of 1045 W for short bursts up to 1 s, enabling it to handle transient loads effectively. The controller accommodates four digital inputs and an analog reference via a ±10 V DC control type, allowing seamless integration with PLCs and motion controllers. Compact dimensions of 53.3 × 45.7 × 15.2 mm and a weight of only 0.037 kg (0.082 lb) facilitate installation in space-constrained enclosures. Robust protections—including short-circuit prevention, I2t current limiting, and over-temperature shutdown—ensure safe operation in demanding environments.

The operating ambient temperature range of 0 to +45 °C, combined with its lightweight construction, ensures compatibility with a wide variety of industrial setups. Its durable design supports reliable long-term performance in assembly lines, robotics, and packaging machinery. The built-in digital Hall sensors enhance motor synchronization, reducing overshoot and vibration during high-speed operation. Certified fault protection and thermal monitoring extend component life and minimize maintenance downtime. In industrial automation, the BTM-055-20 delivers efficiency, repeatability, and confidence for complex motion control tasks.
