Pepperl+Fuchs K-Series Switch Amplifier

Model: KCD2-E3 Part Number: 18356

1. General Description

The KCD2-E3 is a single-channel, isolated switch amplifier from the Pepperl+Fuchs K-Series. It is designed to operate as an interface between a NAMUR sensor (or a dry mechanical contact) located in a general-purpose area and a control system. It provides a clean, isolated 3-wire transistor (PNP) output signal, protecting the control system from field disturbances. The compact housing is designed for easy mounting on a standard DIN rail.

Key Features

• 1-Channel Isolated Barrier: Provides galvanic isolation between the input and output circuits.
• NAMUR Sensor Input: Conforms to DIN 19234 (NAMUR) standards for proximity sensors.
• Transistor Output: Provides a standard 3-wire PNP, normally open output signal.
• Wide Supply Voltage: Operates on a flexible 10 to 30 VDC power supply.
• Compact DIN Rail Housing: Part of the modular K-Series for high-density panel mounting.

3. Connection Diagram

The device features two distinct circuits: the sensor input and the power/output circuit.

• Input (Terminals 1 & 2):
  • Terminal 1: Connect the positive (+) lead of the NAMUR sensor.
  • Terminal 2: Connect the negative (-) lead of the NAMUR sensor.
• Supply & Output (Terminals 3 & 4):
  • Terminal 3: Connect the positive (+) of the 10-30 VDC power supply.
  • Terminal 4: This is the switched PNP signal output. The negative of the power supply provides the common ground for the load
