Beckhoff KL2798 Bus Terminal

Description

The KL2798 is an 8-channel solid state relay output terminal designed for the Beckhoff Bus Terminal system. This module provides high-density, potential-free switching for AC and DC loads up to 30 V AC or 48 V DC. With a capacity of 2 A per channel and a total sum current of 10 A, it is an effective solution for space-saving control of multiple low-voltage loads. The terminal utilizes a 2-wire connection technology and features robust electrical isolation (500 V) between the K-bus and field potential.

Features

• 8-channel solid state relay outputs (make contacts)
• Potential-free switching for 30 V AC / 48 V DC loads
• Maximum output current: 2 A per channel (∑ 10 A)
• 2-wire connection technology
• Compact design for high-density DIN rail mounting
• Robust isolation (500 V K-bus/field potential)

Installation Guidelines

• Mounting: Install the KL2798 on a standard 35 mm DIN rail. Ensure the terminal is securely locked into place for proper power contact alignment.
• Wiring: Uses 2-wire connection technology. Ensure conductors are sized to support the 2 A per channel load requirements.
• Circuit Protection: Note that this terminal is not internally short-circuit proof. External fusing or protection must be installed to manage peak currents and short-circuit conditions.
• Environment: Ensure ambient temperatures remain within 0 degC to 55 degC and humidity levels do not exceed 95% (non-condensing).
• Isolation: Respect the breakdown voltage of 80 V when designing external circuits connected to these relays.
