Product Description:

The KL2184 Bus Terminal is a digital output module with four ground switching channels. It links binary control signals from automation systems to process level actuators. The terminal offers electrical isolation between control and field levels. It supports direct output switching and monitors output states using LED indicators.

The KL2184 bus terminal by Beckhoff operates on a 24 V DC supply with a voltage tolerance of – 15 % to + 20 %. Each of the four outputs supports a maximum load current of 0.5 A and is short circuit proof. The outputs can drive ohmic, inductive or lamp loads. The device handles short circuit currents under 7 A and maintains a breaking energy of less than 100 mJ per channel. It includes reverse voltage protection to prevent damage from incorrect polarity. The connection technology supports both 2-wire and 3-wire configurations. The bus terminal ensures reliable electrical isolation of 500 V between the K-bus and field potential. Current consumption of the terminal from the power contacts is typically 30 mA plus the connected load while K-bus consumption is around 9 mA. The terminal integrates into automation networks without needing any address or configuration settings.

The KL2184 bus terminal’s bit width in the process image is four outputs. It conforms to EMC standards EN 61000-6-2 and EN 61000-6-4 for electromagnetic immunity and emission. The KL series bus terminal is rated IP20 that means it is protected against solid objects larger than 12 mm but not against water. It operates reliably in environments with temperatures ranging from 0 °C to 55 °C. The unit weighs approximately 70 grams that makes it lightweight for DIN rail installations. Each output of the model is monitored using integrated LEDs that indicate the signal state clearly for operational diagnostics.
