Product Description:

The KL2904 Beckhoff digital output terminal is a bus terminal from the manufacturer. This terminal is designed with four channels. The product incorporates EtherCAT technology for its operation. This devices handling is to be undertaken only by trained specialists with expertise in control and/or automation technology. The unit has to be used only as per the instructions given in its manual. It must not be disposed off as domestic waste. This terminal can be commissioned only after reading and understanding its operating instructions.

The product ensures safe operation only if it is used in a machine that complies with the machinery directives. This device is to be operated in protected workplaces as it is designed using electrostatic-sensitive components. The units safety function is at risk if there are wiring errors. It is capable of switching 24 VDC actuators with a current of up to 0.5 A for each channel. This terminal turns off automatically when it encounters a fault. The product mounting is done in a horizontal orientation. This device encompasses signal LEDs on its housing. The unit cannot be operated near transmitters, radios, or high-frequency systems. Its components must be de-energized before working on them.

This digital output terminal helps in the decentralized connection of actuators and sensors in a control system. The product is mainly deployed in building management and industrial automation applications. This device has three power contacts through which the operating voltage is passed to its terminals. The product facilitates the connection of common safety actuators and sensors. This device depicts Type B classification. The unit supports side-by-side installation with other terminals. The unit transportation and storage must be done under the specific environmental conditions. It has a possibility of getting damaged if its LED strip is pressed.
