The 1771-HSAR IMC Servo Controller Module by Allen-Bradley is designed to seamlessly integrate into advanced control systems with its 96-KB lithium battery memory cartridge, pivotal for storing crucial application programs and AMP parameters. Its longevity is underscored by the lithium battery, which can back up the memory module for up to 10 years and typically lasts 3 years on its own. Equipped with a versatile power supply module supporting 120V AC or 220V AC, this controller module also features an AUX FDBK 15-pin connector for auxiliary encoder power and feedback, alongside a 9-pin RS-232 connector for MML program testing and AMP parameter management. A robust connection suite, including various cables like the 1771-PS7 power connector and the 1771-CT50 RS-232 connector, ensures optimal compatibility and connectivity, further enhanced by optional support for a Hand-Held pendant for easy system adjustments.
