Product Description:
The KL2184 is an I/O terminal produced by Beckhoff within the KL Analog Input Modules series. Despite the series designation, this terminal provides four digital switching channels that allow a controller to energize field devices directly from the terminal strip. It is intended for installation in distributed Bus Terminal systems, where compact modules distribute control signals without requiring separate relays. By translating low-level bus commands into switched power for connected loads, the module simplifies machine wiring and supports flexible expansion of industrial automation systems.
Each channel uses 1-wire connection technology, so the load side requires only a single conductor in addition to the shared supply, reducing wiring density inside the panel. The outputs operate at a nominal control voltage of 24 V DC, matching the standard auxiliary power rail used in many machinery cabinets. Continuous current is limited to 0.5 A per channel, allowing the terminal to drive small solenoids or indicator lamps without external interposing relays. The terminal provides 4 outputs, giving a direct mapping between PLC output bits and connected field devices. Mechanical installation uses a 35 mm DIN rail latch, enabling straightforward placement within a cabinet row.
The output stage supports resistive, inductive, and lamp loads, so small heaters, coils, and filament indicators can be switched from the same terminal. In the controller memory, the terminal occupies only 4 output bits, minimizing process-image consumption when many channels are connected to the bus. The housing has an IP20 rating, restricting the terminal to enclosed cabinets while protecting against accidental finger contact with hazardous internal parts. Semiconductor monitoring circuitry makes the channel set short-circuit protected, helping prevent output-stage damage if a connected load or conductor develops a fault. Additional reverse-voltage protection helps protect the internal drivers against damage caused by an incorrectly connected external voltage. These protective functions operate electronically and avoid the need for individual mechanical protection devices on the terminal outputs.
