Siemens SIMATIC S7-1500 Digital Input Module DI 16xNAMUR HF
Siemens SIMATIC S7-1500 Digital Input Module DI 16xNAMUR HF.
The Siemens SIMATIC S7-1500 digital input module 6ES7521-7TH00-0AB0 (DI 16xNAMUR HF) is designed for high-frequency input signals. It features 16 channels that can be configured in groups of 8 and are specifically designed for 8.2 V NAMUR encoders. The module provides sensor supply at 8.2 V and offers adjustable input delays from 0.05 to 20 ms.
This module is ideal for use in process automation, hazardous areas, and applications requiring reliable digital input from NAMUR sensors. It supports advanced features such as an integrated counting function up to 20 kHz, pulse stretching, chatter monitoring, signal inversion diagnostics, and hardware interrupts. The front connector (screw or push-in terminals) must be ordered separately.
