ABB RTAC-01
Product Name: ABB RTAC-01 Pulse Encoder Interface Module
Product Description:
The ABB RTAC-01 is an option module designed to integrate encoder-based feedback into ABB drive systems, specifically the ACS800 and DCS800 series. It provides a differential or single-ended interface for a digital pulse encoder, allowing for precise speed and position data to be fed back to the drive. This module fits into an RMIO board or an external I/O Module Adapter (AIMA-01). It supports operation from either a 15 VDC or 24 VDC encoder signal with a maximum frequency of 200 kHz.
Key Characteristics:
- Encoder Support: Channels A, B, and Z for differential or single-ended signals.
- Output Voltages: +24 V DC ±10%, 5 W max., short-circuit proof; +15 V DC ±10%, 5 W max., short-circuit proof.
- High Frequency Support: Operates at up to 200 kHz.
- Precision Feedback:
- Speed Feedback Resolution: 0.00305% (15 bits).
- Speed Feedback Accuracy: 50 ppm.
- Cable Lengths (Maximum):
- Differential push-pull: 300 m.
- Single-ended push-pull: 200 m.
- Open collector/emitter: 100 m.
- Electrical Isolation: Provides 1.5 kV AC isolation between logic and earth for enhanced safety.
