Siemens 6SE7090-0XX84-3DB0 SIMOVERT MASTERDRIVES DTI Card

Product Description

High-Speed Encoder Signal Processing for Masterdrives

The Siemens 6SE7090-0XX84-3DB0 is a specialized Digital Tachometer Interface (DTI) module engineered for the SIMOVERT MASTERDRIVES Vector Control (VC) and Motion Control (MC) series. This module serves as a high-precision bridge between digital pulse encoders and the drive's control electronics. It is specifically designed to handle and convert signal levels between different encoder standards, supporting both TTL (RS422) and HTL (High Threshold Logic) signals. By providing electrical isolation and signal conditioning, the DTI ensures that the drive receives clean, noise-free speed and position feedback even in electrically noisy industrial environments.

Versatile Power Management and Signal Reliability

The 6SE7090-0XX84-3DB0 features integrated power supply management for connected encoders, supporting various voltage requirements. It can utilize an internal 15 VDC supply or accept an external 24 VDC input to power the tachometer system. With a maximum switching frequency of 400 kHz, the DTI module is capable of processing high-resolution signals from high-speed motor spindles or precision positioning axes. Its robust circuitry is designed for cabinet mounting, allowing for reliable operation across a wide temperature range of 0 to 55 °C, making it a critical component for the ongoing maintenance of legacy MASTERDRIVES systems.
