DEA 300 Digital Input Module 24 VDC for 300 systems

The DEA 300 Digital Input Module is a 24 VDC digital input module designed for 300 series automation systems, ideal for industrial applications that require reliable signal acquisition. Its compact size and DIN‑rail mounting make it easy to integrate into both new and existing control panels.

The version with part number 700-321-1BH02 provides 16 digital inputs at 24 VDC, while the 700-321-1BL00 variant offers 32 digital inputs at 24 VDC. These two configurations allow you to choose the most suitable I/O density for your panel layout and application needs.

Each input channel is designed to reliably detect standard 24 VDC logic levels, with high immunity to electrical noise and disturbances. Electrical isolation between the backplane bus and field signals helps protect the control system from overvoltages and potential differences coming from the field side.

DEA 300 modules are equipped with status LEDs for each digital input, greatly simplifying local diagnostics and maintenance by allowing quick visual verification of signal presence. The robust construction makes them suitable for continuous operation in demanding industrial environments.

These digital input modules are an excellent choice for expanding existing systems as well as for new automation projects, in applications such as machinery, production lines, process plants and infrastructure. Compatibility with 300 series systems ensures straightforward integration into existing control architectures.
