Information About 20-750-ENC-1
The 20-750-ENC-1 is part of the Allen-Bradley PowerFlex 750 family, designed to integrate encoder-based feedback into adjustable frequency drives. It supports both single-ended and differential operation, with a constant current sink operation drawing about 10 mA. This module operates within an input voltage range of 5 to 15 VDC, with a minimum high-state voltage of 3.5 VDC and a maximum low-state voltage of 0.4 VDC. It can handle input frequencies up to 250 kHz, making it suitable for high-speed feedback applications. Installation compatibility varies by drive and frame size, with port allocation ranging from ports 4 and 5 on smaller frames to ports 4–8 on larger PowerFlex 755T drives. With external power support and long cable lengths of up to 183 m (600 ft) at 12 VDC, the 20-750-ENC-1 ensures flexibility in industrial motion and positioning control.
Key Features:
- Drive Compatibility: Works with PowerFlex 753, 755, 755TL, and 755TR drives for feedback integration.
- Operation Modes: Supports single-ended, differential, and constant current sink operation for flexibility.
- Input Voltage Range: Operates from 5–15 VDC with stable performance in industrial environments.
- Signal Levels: Minimum high-state voltage of 3.5 VDC and maximum low-state voltage of 0.4 VDC for reliable switching.
- Frequency Response: Handles input frequencies up to 250 kHz for high-speed motion feedback.
- Cable Support: Maximum cable length of 30 m at 5 VDC and 183 m at 12 VDC for installation versatility.
- Power Options: Can be powered by the drive or an external encoder supply, supporting flexible configurations.
- Terminal Connections: TB1 14-pin terminal block for encoder signal and voltage wiring.
The 20-750-ENC-1 delivers the reliability and precision required for position feedback and control in advanced drive applications.
