MDT BE-04024.02 Binary Input 4-Fold 2TE REG 24V AC/DC

The MDT BE-04024.02 is a KNX binary input module with four independent channels, designed for DIN rail mounting in a compact 2-module (2TE) housing. Unlike basic input modules, it accepts both dry contacts and 24V AC/DC voltage signals, making it adaptable to a wide range of sensors and switches. Each input can be individually configured for switching, dimming, blind control, value transmission, scene recall, or pulse counting, providing flexibility for diverse building automation tasks.

Highlights

• 4 binary inputs, individually configurable
• Supports dry contacts and 24V AC/DC signals
• Compact 2TE DIN rail housing
• Low bus power consumption (< 0.3 W)
• Integrated programming LED for ETS commissioning

In daily use

Connect conventional switches, push buttons, motion detectors, or window contacts to the screw terminals. Each input can trigger KNX telegrams for lighting, shading, HVAC, or alarm functions. The module operates from 0°C to +45°C and is suitable for distribution boards in residential and commercial buildings.
