The Allen-Bradley 1771-ES PLC 5 Servo Encoder Feedback Expander Module is designed for high-precision applications within the Servo Positioning Assembly, offering incremental digital encoder feedback and requiring two slots on the 1771 I/O chassis. It features a 12-bit DAC for precise analog output control with ±10V DC isolated maximum voltage, and provides versatility with user-selectable encoder input modes of differential at 250 kHz or single-ended at 20 kHz, along with three programmable encoder multipliers (x1, x2, x4). With a robust design accommodating operating temperatures from 32° to 140°F, this module supports programmable positioning up to ±999.9999 inches and speed ranges from 0.0001 to 9990 inches per minute, ensuring precision and adaptability for complex applications.
