Performance Parameters:

• Signal isolation and conversion for multiple input/output channels

• Prevents signal distortion or equipment damage caused by ground potential differences or electromagnetic interference

Material Composition: Industrial-grade materials suitable for DIN rail mounting and control cabinet environments

Structural Characteristics:

• Mounting: DIN rail mounting (standard 35mm)

• Interface Type: Terminal block wiring on input side; terminal block wiring on output side (one-to-one correspondence with inputs)

• Dimensions: Standard DIN rail module size

• Modular design for easy integration

Working Principle: The IBC module isolates signals between controllers or I/O modules and external devices. It provides complete electrical isolation between input and output circuits, preventing ground loop interference and ensuring signal integrity. Analog signals (4-20mA, 0-10V) and digital signals (dry contacts, 24V DC) pass through the isolation barrier without electrical continuity.

Advantages and Strengths:

• Prevents signal distortion and equipment damage from ground potential differences and electromagnetic interference

• Exceptional performance in environments with strong electromagnetic interference, high voltage surge risks, and complex grounding

• No complex programming required

• Built-in microprocessor for complex control logic and diagnostic information processing

• Real-time valve status monitoring (friction, stroke time) enabling predictive maintenance

Applicable Industries:

• Energy and power generation

• Chemical and petrochemical

• Metallurgy and mining

• Water treatment

• Oil and gas, pulp and paper

Model Series: Valmet DNA Automation Platform / IBC (Isolated Bus Coupler) Series

Installation Requirements: DIN rail mounting in control cabinets; terminal block wiring for signal connections

Usage Precautions:

• Input and output terminals must be correctly matched to signal types

• Confirm compatibility with Valmet DNA systems

• Suitable for environments with strong electromagnetic interference
