• Assembly line automation
• Textile machinery
• Printing and labeling equipment

Installation Requirements:

• Mount on standard 35 mm DIN rail (EN 60715)
• Ensure adequate ventilation spacing between modules (min. 10 mm)
• Terminal wiring: use stranded or solid copper conductors, 0.14–2.5 mm²
• Do not exceed maximum per-channel current of 0.5 A
• Verify correct polarity: 24V DC to load, output sinks to 0V

Usage Precautions:

• Do not connect inductive loads without external flyback diodes (for loads > 0.1 A inductive)
• Do not exceed the total module current of 6 A
• Do not apply AC voltage to transistor outputs
• Ensure proper grounding of the 24V DC supply common (0V)
• Replace modules only with identical B&R X20BM12 units

Advantages & Highlights:

• Fast switching speed (< 1 ms) for high-speed applications
• Full channel isolation ensures noise immunity in multi-axis systems
• Tool-free wiring with push-in terminals reduces installation time by up to 70%
• Built-in diagnostics enable predictive maintenance and reduce downtime
