The Beckhoff KL2488 is an industrial 8-channel digital output Bus Terminal designed for automation systems requiring reliable 24 V DC ground-switching (mass/negative switching). Unlike standard positive-switching modules, the KL2488 switches the ground (0 V) connection to actuate connected loads.

• Outputs: 8 digital channels using space-saving 1-wire connection technology.
• Electrical Parameters: Nominal voltage of 24 V DC with a maximum output current of 0.5 A per channel.
• Load Compatibility: Supports ohmic, inductive, and lamp load types.
• Physical Profile: Highly compact layout (12 mm width, ~70 g) optimized for dense control cabinet installations via 35 mm DIN rail mounting.
• Current Consumption: Draws 18 mA from the K-bus.
