Pepperl + Fuchs KFA6-SR2-Ex2.W 2-Channel Switch Amplifier (Intrinsic Safety Barrier)

The Pepperl+Fuchs KFA6-SR2-Ex2.W, order code 103373, is a high-integrity 2-channel switch amplifier and isolated barrier from the K-System series, engineered for intrinsic safety applications in hazardous areas. This module provides a safe and reliable method for transferring two independent digital signals from devices located in potentially explosive atmospheres, such as dry contacts or NAMUR proximity sensors, to control systems in the safe area.

Acting as a dual-channel intrinsic safety barrier, the KFA6-SR2-Ex2.W limits energy to the hazardous area, preventing ignition. Each channel processes its input signal independently and provides a corresponding isolated relay contact output in the safe area. The unit is powered by a 230 V AC supply and features secure screw terminals for easy installation on a 35mm DIN rail.

The KFA6-SR2-Ex2.W is compliant with relevant intrinsic safety standards (indicated by 'Ex' and specific Ex markings) and is often suitable for functional safety applications (e.g., up to SIL 2), ensuring high safety integrity. It's an essential component for safely interfacing multiple digital field signals from hazardous locations into your industrial automation and control systems.

Key Characteristics:

• Function: Intrinsic Safety Barrier and 2-Channel Switch Amplifier.
• Channels: 2 independent channels.
• Input: Supports dry contacts and NAMUR proximity sensors from hazardous areas for each channel.
• Output: Two independent Isolated Relay Contact outputs in the safe area.
• Supply Voltage: 230 V AC.
• Mounting: 35mm DIN Rail.
• Terminals: Screw Terminals.
• Safety: Provides intrinsic safety (Ex) and suitable for functional safety (SIL) applications.
• Isolation: Electrical isolation between inputs, outputs, and power supply.

The Pepperl+Fuchs KFA6-SR2-Ex2.W provides a space-saving and reliable solution for safely integrating two digital signals from hazardous locations into your industrial control architecture.
