Greenwich Instruments 20 W 24V 3 Phase Motor Controller GSM 2

Greenwich Instruments GSM 2 is a high-performance 20 W Motor Controller designed for unipolar stepper motors operating at 24V with a 3 phase input configuration. This stepper motor driver board supports motors with four phases and a wiring configuration of five, six, or eight wires, delivering a current rating of up to 2A per phase. It is ideal for industrial automation and control applications requiring precise motor positioning and speed control.

The GSM 2 controller offers selectable stepping modes, including full, half, and wave step modes, to optimize motor operation based on application needs. Speed adjustment can be achieved via an onboard trimmer potentiometer for the internal clock or externally through logic connectors, providing flexible control options.

Safety and control are enhanced by enable and disable inputs, enabling multiple start and stop control schemes. The motor controller is fully compatible with TTL, LS, and CMOS logic levels, ensuring integration ease within various control systems. Open drain power MOSFET outputs facilitate efficient phase switching for smooth motor performance.

Measuring 61mm in length, 46mm in width, and 15mm in depth, the compact GSM 2 board fits easily into diverse industrial setups. It is built to operate reliably under temperatures up to 65°C without compromising functionality.

This motor controller is widely applicable in industrial automation, robotics, manufacturing machinery, HVAC systems, and laboratory instrumentation where stepper motor control is essential. The robust design ensures long-term reliability and performance in demanding environments.
