BECKHOFF KM2604 Bus Terminal Module

The KM2604 is a 4-channel relay output Bus Terminal module designed for switching high-voltage loads in industrial applications. Manufactured by BECKHOFF, this module features four change-over contacts capable of handling up to 16 A, making it suitable for controlling ohmic, inductive, and lamp loads. The KM2604 ensures reliable signal isolation with a rated surge voltage of 2.5 kV and is integrated directly into the I/O system, requiring no additional address or configuration settings.

Features

• 4-channel relay output with change-over contacts
• Nominal switching voltage of 250 V AC or 30 V DC
• High load capacity: 16 A nominal switching current
• Integrated surge protection (overvoltage category III)
• Suitable for high starting current applications (lamp loads/electronic ballasts up to 25 A)
• Long operational lifespan (5 x 10^6 mechanical cycles)
• Compact DIN rail mountable design

Applications

• High-power actuator control
• Industrial lighting and electronic ballast switching
• Relay control logic for automation systems
• HVAC and building automation load switching

Technical Specifications

Installation Guidelines

• Install the module on a 35 mm DIN rail in accordance with EN 60715 standards.
• Ensure adequate spacing for heat dissipation if multiple modules are installed in high-load scenarios.
• The module does not require address or configuration settings; ensure it is properly snapped onto the K-bus interface.
• Operate within the specified ambient temperature of 0 to +55 degC.
• Ensure wiring follows standard electrical codes, particularly when handling 230 V AC loads, to maintain safety and EMC compliance.
