KL2702

What does this digital output module do?

This module is used to switch external electrical loads from a control system. It functions as a 2-channel solid state output terminal and is designed to switch voltages up to 230 V AC/DC.

How many outputs are available?

It provides two output channels. Each channel can be used to switch a connected load, making it suitable for applications where two separate output points are required within one compact terminal.

What voltage range can it switch?

The unit is intended for switching loads up to 230 V AC/DC. This makes it suitable for a range of mains-voltage switching tasks where compact solid state output control is needed.

What is the output current capacity?

This version is rated for up to 0.3 A. When selecting a module for an application, the connected load should remain within the stated electrical limits of the Beckhoff KL2702.

Does it use mechanical relays?

No. It uses an electronic solid state switching element based on a high-power MOSFET rather than a mechanical relay contact. This means there are no moving relay parts involved in normal switching operation.

Are the two output channels independent?

Yes. The two outputs are independent, allowing separate control of two connected loads from the same module.

How can I tell if an output is active?

The module includes LED indication for each channel. These status LEDs provide a simple visual way to check the signal state of output 1 and output 2.

What does a 4-wire system mean for this module?

In practical terms, the module is arranged for wiring with the relevant supply and output connections used by the terminal, including the switched voltage path and associated conductors. This helps it integrate into control panels where clear load-side wiring is required.

What types of applications is this module commonly used for?

It is commonly used for switching mains-voltage loads in industrial automation systems, such as signalling devices, contactor interfaces, lamps and other electrical loads that fit within the module’s switching limits.

Why would someone choose a solid state output module instead of a conventional relay output?

A solid state output module is often chosen where low-wear electronic switching is preferred. Because this design uses a semiconductor switching element, it avoids the mechanical contact wear associated with traditional relay-based switching.
