BMXDDM16022 | Schneider 8DI/8DO Solid State Module

Product Overview

The Schneider Electric BMXDDM16022 is a mixed discrete I/O module for the Modicon X80 automation platform. It combines 8 discrete inputs (24 V DC) and 8 solid state outputs in a single compact module. The transistor outputs provide fast switching for DC loads, making this module ideal for high-speed counting, positioning, and discrete control applications where relay response times are insufficient.

FAQ

Q: What is the difference between BMXDDM16022 and BMXDDM16025?
A: BMXDDM16022 has solid state (transistor) outputs for 24 V DC; BMXDDM16025 has relay outputs for AC/DC.

Q: Can I switch AC loads with BMXDDM16022?
A> No. The solid state outputs are designed for 24 V DC loads only. For AC loads, select BMXDDM16025.

Q: Is there a severe environment version?
A: Yes. BMXDDM16022H is available with enhanced coating for harsh environments.

Installation Guide

1. Install the module in any X80 rack slot
2. Attach a 20-pin removable terminal block
3. Wire 24 V DC sensors to the input terminals
4. Wire 24 V DC loads to the solid state output terminals
5. Verify polarity on output connections to prevent damage
6. Energize the rack and confirm channel LEDs display correct states

Selection Tips

• Select BMXDDM16022 for fast-switching 24 V DC output applications
• For AC or isolated relay outputs, choose BMXDDM16025
• For harsh environments, select BMXDDM16022H
• Verify load current requirements match solid state output ratings
• Ensure all loads are 24 V DC before connecting to outputs
