Description

Siemens SIMATIC S7-1500 digital input module DI 16x24VDC HF is used for acquiring 16 digital inputs at 24 V DC levels from field sensors such as limit switches, pushbuttons and proximity switches. The module offers parameterizable input delays for noise suppression, diagnostic functions for channel and group faults, and status LEDs for each channel group. It is designed for space-saving installation in SIMATIC S7-1500 automation systems and connects directly to the backplane bus.

Key features

• 16 digital inputs for 24 V DC digital input signals (DI 16x24VDC HF). • Parameterizable input delay for suppression of contact bounce and interference. • Integrated channel and group diagnostics with status LEDs. • Compact module width for high channel density in the control cabinet. • Direct connection to SIMATIC S7-1500 backplane bus – no additional wiring module required.

Typical applications

• Machine and plant automation with SIMATIC S7-1500 controllers. • Packaging, material handling and production lines requiring high digital I/O density. • Retrofit and expansion of existing S7-1500 panels with additional digital I/O. • Acquisition of limit switches, proximity sensors and operator pushbuttons.
