It installs in any 1771 I\/O chassis and pairs with the 1771-PS7 power supply module rated at 120V AC and 1A. Weighing approximately 1.36 kg, this controller receives encoder and resolver feedback through a 50-pin I\/O connector and delivers ±10V DC analog commands for precise multi-axis motion control.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Configuration\u003c\/h2\u003e\n\u003cp\u003eThe controller package includes a memory module, power module, encoder module, resolver, and optional hand-held pendant. It uses 96KB 1771-HM3A battery-backed memory cartridges to store AMP parameters and MML downloaded programs. The front-panel RS-232 port supports program upload\/download and connects to T45 and T50 ODS via hand-held pendant for debugging. Encoder feedback is provided through an isolated 10V DC output with 250 kHz differential, single-ended input capability.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%;
